Problem
Four identical point charges of +2μC are fixed at the four corners of a square of side 0.10m. Taking one of the charges as the charge of interest,
(a) calculate the magnitude of the net electrostatic force acting on it due to the other three charges,
(b) specify the direction of this net force with respect to one of the sides of the square.
