find the ratio of electrostatic force and gravitation force for 1. between two electon 2. between two proton 3. one electron and proton.

The Charge of a Proton and an Electron is same i,e

 

The Charge on Electron is Negative of the above.

 

Let us assume that the charges are seperated by a distance of 1 cm.

 

The Electrostatic Force between Two Protons or Two Electrons is

 

 

Gravitational Force between two Protons is

 

 

Gravitational force between two Electrons is

 

Where m₁ and m₂ is the mass of electron.

 

Electrostatic force between one Proton and Electon is

 

 

Gravitational Force between a Proton and electron is

 

 

 

Now the Ratio of electrostatic force and Gravitational force for

 

1) Between two electron is

 

 

Where E.F. means Electrostatic Force and G.F. means Gravitational Force.

 

2) Between Two Proton is

 

 

C) between one electron and proton is
