If a positive charge is shifted from a low-potential region to a high-potential region, the electric potential energy
(c) remains the same
(d) may increase of decrease
The electric potential energy, E, of a positive charge, q, in a potential, V, is given by E = qV. As the charge is moved from a low-potential region to a high-potential region, i.e. as V is increased, E will increase.
