A raindrop of mass 4.0 mg and radius 2.0 mm has acquired an electric charge of 15x10^-15 C. The raindrop is located at the bottom of a cloud that is 500 m above the surface of the earth where the electric potential is -10^9 V with respect to the ground. What is the ratio of the electric potential energy of the raindrop compared to the gravitational potential energy?
ANS: -7.7x10^-4 I just don't know how to solve the problem.

Part A: If a spherical raindrop of radius 0.700 mm carries a charge of -2.40 pC uniformly distributed over its volume, what is the potential at its surface? (Take the potential to be zero at an infinite distance from the raindrop.) Part B: Two identical raindrops, each with radius and charge specified in part (A), collide and merge into one larger raindrop. What is the radius of this larger drop, if its charge is uniformly distributed over its volume? Part...
