The force between two electrons separated by a distance r varies as

Force between two charges separated by a distance r varies as r^(2) ?

Suppose that the gravitational force between two bodies separated by a distance R becomes inversely proportional to R (and not as (1)/(R^(2)) as given by Newton's law of gravitation). Then the speed of a particle moving in a circular orbit of radius R under such a force would be proportional to

Calculate the ratio of electromagnetic force to gravitational force between two protns separated by some distance.

Gravitational force between two point masses m and M separated by a distance r is F . Now if a point mass 3m is placed very next to m , the total force on M will be

Gravitational force between two point masses m and M separated by a distance r is F . Now if a point mass 3m is placed next to m , what will be that a. force on M due to m , b total on M ?
