(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 ?

A block of mass M si suspended by two strings angles theta_(1) and theta_(2) with the horizontal. Find the tensions in the strings.

Two points charges are placed on x-axis as shown, a = 1 cm, q = 1muC , mass of each particle m=6g . The charges are tied at the end of an inextensible string of length 2a. The whole system is free to move on a horizontal frictionless surface. What is the tension in the string when velocity is maximum.

Two charged particles, having equal charges of 2.0xx 10^(-5) C each, are brought from infinity to within a separation of 10 cm. Find the increase in the electric potential energy during the process.

Two particles of mass m and 2m are connected by a string of length L and placed at rest over a smooth horizontal surface. The particles are then given velocities as indicated in the figure shown. The tension developed in the string will be
