A uniform electric field of magnitude 250 V/m is directed in the positive x direction. A +12.0 micro coloumb charge moves from the origin to the point (x, y) = (20.0 cm, 50.0 cm).
a) What is the change in the potential energy of the charge-field system?
b) Through what potential difference does the charge move?
The solution states the change of potential energy and the coloumb charge caused by its movement. The answer highlights the movements of coloumb charges and their effects.
