A particle having a charge of `2.0xx10^(-4) C` is placed directly below and at a separtion of 10 cm from the bob of a simple pendulum at rest. The mass of the bob is 100g. What charge should the bob be given so that the string becomes loose?

(a) Two charged particles , each charge q , are joined by an insultating string of length L and system is kept on smooth surface. Find tension in the string. (b) A particle having charge Q_(0) is placed directly below and at separation d from the bob of simple pendulum at rest. The mass of the bob is m . What charge should be given to bob so that string becomes loose ? ( c) A particle A having charge q and mass m is placed at the bottom of a smooth inclined plane of inclination theta . Where should a block B , having same charge and mass , be placed on the incline so that it may remain in equilibrium ?
