Chapter 26, Problem 38EAP

The electric field in a region of space is $E_x=5000x\text{ V/m}$ ,

where x is in meters.

a. Graph Ex versus x over the region $\text{-l m }\le x\le \text{1 m}$ .

b. Find an expression for the potential V at position x. As a

reference, let V = 0 V at the origin.

c. Graph V versus x over the region — $\text{-l m }\le x\le \text{1 m}$ .
