Assume that 10 J of work is needed to push a charge, at rest, into an electric field. After the charge is released there, it flies back to its starting position and its kinetic energy there will be
a) zerob) more than 10 Jc) 5 Jd) 10 Je) impossible to predict without additional information

When charge reaches the maximum position kinetic energy is zero and when it reaches its original position then the kinetic energy will be equal to energy at which it is moved.

Kinetic energy when it reaches its original position is equal to 10 J.

the correct answer is option D
