Electrostatic force Fe between two charges q1 and q2  that are separated by distance d is

where K= 1/(4πεo) = 9 × 109 N m2 C-2 is Coulomb's constant.

If masses of the charges are m1 and m2 , then gravitational attraction force Fg is

where G = 6.674 × 10-11 N m2 kg-2 is universal gravitational constant .

The ratio between electrostatic force to gravitational force is
