Charge q on a small conducting sphere S1 is placed inside a large hollow metallic sphere S2 having a charge Q as shown in figure. The sphere is connected to shell by a conducting wire. The charge on S1 will then be equipotential lines are shown. In the following figure December 2, 2020 Category: Cengage NEET by C.P Singh , Chapter 1 - Electrostatics , Part 2 , Facebook Messenger WhatsApp Share this:TwitterFacebook Related A conducting sphere S1 of radius r is attached to an insulating handle. Another conduction sphere S2 of radius R is mounted on an insulating stand. S2 is initially uncharged. S1 is given a charge Q brought into contact with S2 and removed. S1 is recharge such that the charge on it is again Q and it is again brought into contact with S2 and removed. This procedure is repeated n times. a. Find the electrostatic energy of S2 after n such contacts with S1. b. What is the limiting value of this energy as n→∞ ?A solid conducting sphere having a charge Q is surrounded by an uncharged concentric conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V. If the shell is now given a change of - 3Q, the new potential difference between the same two surfaces isBetween two large parallel plates, a uniform vertical field E is set up as shown in figure. Find the period of oscillation of the pendulum, if the pendulum of length L having a small conducting sphere of mass m and charge +q is oscillating between the plates.
