It is the pre lab working "Charge to mass ratio of the electron" (e/m). This section based on data collection from Motion of Electrons in the e/m Apparatus and the Helmholtz Coils.Please help me do these question. Thanks so much in advance.

Data Acquisition Now you will take data and analyze it to extract the charge to mass ratio. In order to do so, the parameters of the Helmholtz coils need to be specied. Each coil contains N = 132 loops of wire, and each loop has a radius of R = 15.0 cm. The accompanying Excel template you will use already has these values as inputs. but this is where they come from. When you are ready to begin taking data, please follow these steps: 1. Download the accompanying Excel template from D2L and save it to the computer. 2. Set the voltage dial on the apparatus to 200 V and adjust the current until the diameter of the electron beam is 8.0 cm. Record the values of the voltage and the current in the appropriate elds in the template. 3. Increase the voltage by 30 V and adjust the current until the diameter of the electron beam is 8.0 cm. Record the values of the voltage and the current in the appropriate elds in the template. 4. Carry out this procedure for 4 more 30 V increments, always making sure that the diameter of the electron beam is 8.0 cm, and ll in the relevant elds of the Excel template. Question 15: Using your answer to Question 12, rearrange it to nd an equation for a line Y : M X that can be plotted to nd elm. What are Y, M, and X in terms of the physical parameters AV, TE, 82, and refine? Question 16: The Excel template generates a plot of AV vs 32. Does your data form a line or a parabola? Which should it form and why? Question 17: The generated graph also contains a best t line. Which t parameter is related to e/m? Question 18: How can you calculate the ratio e/m from this t parameter? Question 19: What is the predicted value for the electron's charge-to-mass ratio, e/m, based on the accepted values 3 = 1.602 X 11319 C and m = 9.11 X 1031 kg? Question 20: What is your experimentally determined value for 12/17:? How does this compare to the accepted value? Express your answer as a percent difference % diff : elm)(ejn:)(:;m)\"' X 100%, where (e/mxp is your experimental value and (e/m)acc is the accepted value
