# Problem: Consider three plastic balls (A, B, and C), each carrying a uniformly distributed charge equal to either +Q, -Q or zero, and an uncharged (neutral) copper ball (D). A positive test charge (T) experiences the forces shown in the figure when brought very near to the individual balls. The test charge T is strongly attracted to A, strongly repelled from B, weakly attracted to C, and strongly attracted to D.What is the nature of the force between balls A and B?a) strongly attractiveb) strongly repulsivec) weakly attractived) neither attractive nor repulsive

The basic law of Electrostatics,

Like charges repel one another while unlike charges attract one another.

The positive test charge is strongly attracted by A, meaning that A is negatively charged.
