How many time electrostatic force greater than gravitaional force?
Usually nuclear force will be compared to the gravitational force. And it is found that nuclear force between the nucleons is 1040 times larger than the gravitational force.
But this question is some what different one. Any way as we take two protons, having mass 1.67 x 10 -27 kg each and get separated by a distance 1 m will have a force of attraction 1.86 x 10 -64 N.
As 1.6 x 10 -19 C is the charge of each proton, then electrostatic force of repulsion between them if separated by 1 m will be 2.3 x 10 -28
Hence as we compare the forces, the electrostatic will be 2.3 x 10 -28 / 1.86 x 10 -64
1.2 x 10 36 times that of the gravitational force.
But in case of two electrons that will be different and in case of one proton and electron that becomes different. Hope one calculate those.
