Question No. 2

How many times are electrostatic forces stronger than the gravitational ones?
A. ${10}^{16}$ times
B. ${10}^{26}$ times
C. ${10}^{36}$ times
D. ${10}^{46}$ times

First, Coulomb constant is approximately 10^20 times greater than the gravitational constant, not the other way around :) Yes, the quality of objects is different, but you are comparing resulting force between them. Eventhough the forces have different natures, the value you can read on your imaginary force meter when comparing is of the same kind.
