Electrostatic repulsive force Fe between protons is

where K = 1/(4πεo ) = 9 × 109 N m2 C-2 is Coulomb's constant , q = 1.602 × 10-19 C is charge on proton and d is the distance between protons.

If elecrostatic repulsive force is equal to weight of proton then

Fe = Fg

Hence if protons are separated by a distance ~ 12 cm , then repulsive electrostatic force between protons equal weight of a proton.

There is one charged tiny spherical oil drop and the magnitude of electric field intensity at a point on its surface is E. If n such drops are combined to make a single drop then what will be the net electric field intensity at a point on the surface of the bigger spherical drop. Assume that charge is uniformly distributed over the volume of oil drop.
