Calculate the ratio of the electrostatic force to gravitational force between two electrons , two protons. At what value of the specific charge of a particle would these forces becomes equal in the case of interaction of identical particles?

Question

Arun · Answer

Gravitational attraction between two electrons is:
Fgrav = G m^2 / r^2

Electrostatic repulsion between two electrons is:
Felec = k q^2 / r^2

The ratio, therefore, is kq^2 / Gm^2.

Now put the values and find the answer.

Similarly you can do for protons
