An uncharged sphere of metal is placed inside a charged parallel plate capacitor. The lines of force will look like

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
When an uncharged sphere of metal is placed in the uniform field of a parallel plate capacitor, due to the field, the negative charges will become concentrated at the top and the positive charges at the bottom, except for the field passing through the geometric centre, all the rest will be attached to the top and repelled by the charges (+ve below).

A simple pendulum has a length l and the mass of the bob is m. The bob is given a charge q coulomb. The pendulum is suspended between the vertical plate of a charged parallel plate capacitor. If E is the electric field strength between the plates, the time period of the pendulum is given by

Obtain the expression for the energy stored in a charged parallel plate capacitro and express it in its three equivalent forms, in terms of capacitance C, charge Q on the plate and potential difference V between the plates. Use this result to show that the energy density, of the electric field E, in a capacitor equals 1/2varepsilon_0E^2 .
