Mars has a mass of 6.421 × 1023kg, and radius 3.4 × 106m. (a) Calculate the gravitational acceleration “g”, at the surface of Mars. (b) Will the gravitational potential approximation given above for Mars be accurate over a larger or smaller range of values of ∆y than that for the Earth? Justify your answer (do the math).
I already answered the question a, but I do not understand what they want for question b.

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.
