1)Three conducting spheres of identical radius but madeofdifferent metals copper, silver and gold. One of thespheres(gold) carries excess charge of +Q. If they are allbroughtinto contact by a metal rod and then separated, what will bethecharge on all three spheres? 2)A certain charge Q is divided into 2 parts. One is qand theother is Q-q. These two charges are then separated bysome distancer. What must be q in terms of Q such that theelectrostaticrepulsive force between the charges is maximum? 3) 3 particls are on the x-axis. Particle 1 of charge q1 isatx= -a and particle 2 of charge q2 is at x=+a. If thenet electrostatic force on particle of charge Q isto be zero, whatmust the ratio of q1/q2 be ifparticle 3 is at x = 0.5a?
