A charged particle q of mass m is in equilibrium at a height h from a horizontal infinite line charge with uniform linear charge density λ. The charge lies in the vertical plane containing the line charge. If the particle is displaced slightly (vertically), prove that the motion of the charged particle will be simple harmonic. Also find its time period

Two small equally charged identical conducting balls are suspended from long threads from the same point. The charges and asses of the balls are such that they are in equilibrium. The distance between them is a=(108)1/3 cm (the length of the threads L>>a). One of the ball is discharged. after sometime both balls comes to rest in equilibrium. what will be the distance b (in cm) between the balls when equilibrium is restored ?

Two identical particles are charged and held at a distance of 1 m form each other. They are found to be attraction each other with a force of 0.027N . Now they are connected by a conducting wire so that charge folws between them. Whe the charge flow stop, they are found to be repelling each other with a force of 0.009 N. Find the initial charge on each particle.
