Electric potential energy

An electron is 0.10 cm from an object with electric charge of + 3.0 X 10^-3 C. (a) Determine the magnitude of the electrical force F_{O on e} that the object exerts on the electron. (b) The electron is pulled so that it moves to a distance of 0.11 cm from the charged object. Determine the magnitude of the electrical force F_{O on e}’ exerted by the charged object on the electron when at this distance. (c) Estimate the work done by the average force pulling the electron

(d) Compare this number to the change in electric potential energy of the electron–charged-object system as the electron moves away from the object. Why should the numbers be approximately equal?
