Prelab 2: Electric Field Name: 1. The electric field strength at some point P, located near several source charges, is measured to be 0.19 N/C. Provide an interpretation of the number 0.19 in this situation. That is, describe the specific information that the number 0.19 conveys in this situation. 2. Suppose an unknown distribution of source charges is arranged in space. You want to find the electric field that is produced. Formulate a series of steps that could be taken to experimentally determine the magnitude and direction of the electric field at some point S. How would a probe charge be used? 3. Three charged particles are arranged on the grid as shown. Two of the particles have a charge of -1 unit, while the third has a charge of +1 unit. Draw an arrow on the diagram to show the direction of the net electric field at location R. Explain your reasoning and or show your work
