The ratio of electrostatic force between two electrons to gravitationforce between them is of the ordera) 10c) 10^3b)1d) 10^42

D) 10^42

Explanation:

The electrostatic force between two electrons is given by

where

k is the Coulomb's constant

q is the electron charge

r is the separation between the electrons

The gravitational force between two electrons is

where

G is the gravitational constant

m is the electron mass

r is the separation between the electrons

So the ratio between the two forces is
