Question

A uniform electric field of magnitude 260 V/m is directed in the positive x direction. A +14.0 µC 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?
What subject do you need help with. "university" is not a school subject the last time I looked.
