Two 10.0-kg balls, each with a charge of 11.0 C, are separated by a distance of
0.500 km in interstellar space, far from other masses and charges.
(b) Calculate the force of gravity between the two balls.
(c) Calculate the electric force between the two balls.

This is straight plug and chug computation. Both are 1/r^2 fields. The gravity pulls them together and the like charges repel. I am not going to do the arithmetic for you.
