Case 1: An electron is released from rest in a uniform electric field.Case 2: A proton is released from rest in a uniform electric field of the same magnitude as in case 1.How does the electric potential energy of the charge-field system behave in these cases?
A)In both cases,the potential energy increases.
B)In both cases,the potential energy decreases.
C)In case 1 the potential energy increases,but in case 2 it decreases.
D)In case 1 the potential energy decreases,but in case 2 it increases.

When a charge is released in an electric field, it moves from a region of higher potential energy to a region of lower potential energy, regardless of whether the charge is positive (proton) or negative (electron). This movement results in a decrease in electric potential energy for both cases.
