Problem
Four point charges are placed at the corners of a square of side 0.20 m in the following order as you move clockwise: +4 μC, −4 μC, +4 μC, −4 μC.
(a) Calculate the magnitude and direction of the net electrostatic force on the +4 μC charge located at the first corner.
(b) If the magnitude of every charge is doubled while keeping their signs unchanged, determine the factor by which the net force obtained in part (a) changes.
