CALC The electric field in a region of space is Ex=5000x V/m , where x is in meters.b. Find an expression for the potential V at position x. As a reference, let V=0 V at the origin.

FIGURE EX26.3 is a graph of Ex . What is the potential difference between xi=1.0 m and xf=3.0 m? <IMAGE>

How far from a 5μC charge will the potential be 100 V?

A −1μC and a 5μC charge lie on a line, separated by 5cm. What is the electric potential halfway between the two charges?
