3. Imagine that the left side of your computer screen (or phone screen, paper, or whatever you are looking at this homework assignment on) had a different electric potential on opposite sides of it that changes linearly from one side the other. The left side has a potential of -25.0V and the right side has a potential of +40.0V. a. In what direction is the electric field across your screen (or paper or whatever)? A. Left to right B. Right to left b. What is the width of your screen or paper (measure it)? c. Calculate the magnitude of the electric field in N/C.
