How do charge and mass relate, and how does mass affect the force between particles?

[PrasadDev]

Hi all,
I would like to know what is the relation between charge and mass (of electron/proton/neutron). How far their masses involve in force that exists between them ?

 

[chrisbaird]

No relation. They are both intrinsic properties of particles. The gravitational force is directly proportional to the mass and the electromagnetic force is directly proportional to the charge. Some people are trying to show that gravity and electromagnetism are different versions of the same thing, but I don't think this has been accomplished yet.

It would be so much simpler if gravity was a small electrostatic correction. However even neutron stars have a gravitational field and they consist of only neutral particles.
