Can you help me fix my lab report base on the comments?

Abstract - Discussion is ok; make sure the method (the action, not just the concept), the results (specifically what did you see?) and the conclusion are clearly stated. Double-check the terminology used; make sure it's consistent with what you tested during the experiment. Introduction/Hypothesis - Interesting discussion; double-check to make sure all your statements are correct. Also, check to make sure the content is relevant (e.g., how do vortex electric fields relate to this experiment?) Need to close the section with a hypothesis statement. Procedure - Content looks ok; need diagrams or pictures to illustrate the setup. Make sure the discussion is written, in past tense, as a narrative rather than a set of instructions. You can drop the "X-component of" when talking about the electric field: your group measured electric field in a direction that helped you avoid having to do vector math, which was the x-direction.. Data/Graphs - Opening and data organization are good; remember to include the uncertainty values for all measured values. Graphs look ok, but need units included for each of the variables . . . you can add those in the titles, or try using overlays on the graphs themselves. Analysis - Again, there' no need to use "x-component": just refer to that as electric field, because that's all it is. As you work thru this section, make sure you don't just describe the trends observed, compare your results against applicable theory (think of the equations you noted in your Intro - which one is applicable for each of the two parts of your experiment?). How can you quantitatively determine if your results agree with theory? (Hint: for each part, you allowed two quantities to vary but held a third one constant: can you verify that mathematically?) By the end of the section you should have a clear assessment of your hypothesis. Conclusion - Good discussion; the only thing you'd need to add are key values from your Analysis section as concrete proof.

Abstract The main focus of this experiment Experiment 51 is to study the relationship between electric field and charge value and distance. The virtual experiment is carried out in two parts, the first part focuses on the patterns between the charge value and the electric field, and the other part focuses on the magnitude and distance relationship between the electric field and the electric field. Experiments have shown that the potential energy is proportional to the charge of the two charges and inversely proportional to the distance between them. The relationship between the two is confirmed by Coulomb's law used to find the electric field. Introduction Electric fields are special substances that exist in the space around electric charges and changing magnetic fields. This kind of matter is different from ordinary objects. Although it is not composed of molecular atoms, it is a special matter that exists objectively, and has objective properties such as force and energy that ordinary matter has. At a certain position in the electric field, a charge q is subjected to the ratio of the electric field force F and its charge Q at that point, which is called the electric field strength at that point, the field strength. The definition E=F/Q. The direction of the positive charge at a certain point is the direction of the field strength at that point, and the electric field strength at each point in the electric field has nothing to do with whether the charge is placed. In the same space, if several stationary charges generate electric fields simultaneously in space, then the field strength at a certain point in space is the vector sum of field strengths generated at that point when each field source charge exists alone. Field strength formula of point charge: The field strength formula generated by point charge Q at a certain point in vacuum is: E=K*Q/r2. Q is the size of the field source charge that generates the electric field. r is the distance from the point of interest to the field source charge.

The definition of field strength is derived from the characteristic that the electric field has a force on the electric charge. It is applicable to both electrostatic fields excited by charge and vortex electric fields excited by changing magnetic fields. The characteristic of the electric field is that it has the effect of electric field force on the electric charge. The direction of the force of the positive charge is the same as that of the electric field, and the direction of the force of the negative charge is opposite to the direction of the electric field. An electric field is a substance that has energy, and the energy of the electric field is greater where the field is strong. Procedure The experiment was performed on a virtual simulator on the website phet.colorado.edu. The simulation is under "Physics", then under "Electricity, Magnets and Circuits" and finally choose "Charges and Fields". Select the Grid button to display coordinates for distances. The "Show Numbers" button is also selected to display value to the vector on the electric field. We also have a Measurer that can show the magnitude and direction of the electric field at that point. Then set a charge at the origin and place the electric field sensor on the x-axis two meters away from the origin. Distance is measured by the distance measurer in the lower right corner of the simulator screen. Measure the X-component of the electric field in 1 nC increments between -5 nC and +5 nC. Since it is at the origin, positive and negative charges can be added or removed to create these numbers. A table was made in lab journal to record the x-component and the corresponding electric field. A charge of +1 nC is placed at the origin and the electric field sensor is placed on the positive x-axis. Created a table documenting the distance and X- component of the electric field in Lab journal. The distance from the electrical sensor to the charge is varied and the X-component of the electric field is measured. Ten different distances

between 0.6 m and 6 m were recorded in the lab journal. Open the LoggerPro to make graphs electric field vs charge and electric field vs distance. Data This experiment was performed in two parts, one looking at charge (electric field vs charge) and the other looking at distance (electric field vs distance) both using the electric field to show the relationship. The first table of the experiment is to look at the charge and relationship of the electric field and compare it to doubling itself. The charge is measured in nC and the electric field is measured in V/m. Charges were recorded between -5 and +5, as shown in Table 1. When the charge is doubled, the value of the electric field is also doubled. When looking at +1 nC, the electric field is recorded as 2.21 V/m, and when the charge is doubled to +2 nC, the corresponding electric field value is 4.40 V/m. The Table 2 section of the experiment looks at distance versus electric field as a function of distance. The distance varied ten times from 0.6 m all the way up to 6.0 m. The electric field (V/m) for all distances is recorded in Table 2. When the distance is doubled, the electric field is reduced by 1/4.
