Problem
Two identical point charges, each of charge q , are separated by a distance r . When r is decreased, the electrical potential energy between the two charges is doubled. Which of the following correctly gives the change to the repulsive force, F , experienced by each of the point charges?
(1) F halves.
(2) F stays the same.
(3) F doubles.
(4) F quadruples.
