A conducting ball is positively charged and another positive point charge is brought closer to the ball.

A positive point charge Q is brought near a neutral metal cube.

A positive point charge q is brought near a neutral metal sphere.

A positive point charge q is brought near a neutral metal sphere.

An agent is moving a positively charged body towards another fixed positive charge. The work done by the agent is

A conducting ball is given a certain charge and fixed at point P. An another point charge of mass 1 gm and charge 20muC when kept at Q (3m, 9m) starts moving with acceleration veca=(1.08hati+1.44hatj)ms^(-2) . The potential at Q is +720 volt. Calculate (a) charge given to ball (b) position of the ball.

Two identical small conducting balls have positive charges q_1 and q_2 respectively. The force between the balls when they are placed at a separation is F. The balls are brought together so that they touch and then put back in their original positions. Prove that the force between the balls now, cannot be less than F.
