state coulomb's law?
Asked by Shyam | 17 Dec, 2018, 12:14: PM
answered-by-expert Expert Answer
Coulombs law of electrostatic state that force (attraction or repulsion) between two static(rest) charge is directly proportional to product of their charge and inversely proportional to square of the distance between them.
Let us assume two positive charge Q1 and Q2 placed at a separation of d then the force  between these charges would be

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.
