B) the electrical potential energy of the charge does not change.

E) the electrical potential energy undergoes the maximum change, but there is no change in voltage.

Question

Quizplus · Accepted Answer

When a charged particle is moved along an electric field line, it experiences a force in the direction of the field (or opposite to it, depending on the charge sign). This results in work being done on the charge, which changes its electrical potential energy. Moving along the field lines represents the path of maximum force exerted on the charge, hence leading to the maximum change in electrical potential energy.
