It takes 10 J of work to push a charge into an electric field.Relative to its starting position it has gained a potential energy of
A)less than 10 J.
B)10 J.
C)more than 10 J.
D)none of the above

Question

Quizplus · Accepted Answer

The potential energy gained by a charge in an electric field is equal to the work done on the charge to move it from its initial position to the final position. Therefore, the potential energy gained by the charge in this case is 10 J, which is equal to the work done on the charge. So the correct answer is B.

It Takes 10 J of Work to Push a Charge
