Two identical balls have the same amount of charge,but the charge on ball A is positive and the charge on ball B is negative.The balls are placed on a smooth,level,frictionless table whose top is an insulator.Which of the following is true?
A)Since the force on A is equal but opposite to the force on B,they will not move.
B)They will move together with constant acceleration.

Although the balls have the same amount of charge, they have opposite signs. So, they will attract each other with the same magnitude of force.
