Two charges, q1 and q2 are separated by a distance r. If q1  will be reduced to one-fourth and the distance between the charges will be reduced to one-half, what will happen to the force between the two charges? ANS. : remains the same

Identical point charges of +2.2 µC are fixed to three of the four corners of a square.
