Problem
A point charge of +2.0μC is placed at a distance of 5.0cm from a point charge of −3.0μC in vacuum.
(a) Calculate the magnitude of the electrostatic force acting between the two charges.
(b) State whether this force is attractive or repulsive and give a brief reason.
(c) Convert the magnitude of the force obtained in part (a) from newtons to dynes.
