A charge q is placed at O in the cavity in a sphereical uncharged conductor. Points S is outside the conductor. If q is displaced from O towards S (still remaining within the cavity)

Asseration: A point charge q is placed at centre of spherical cavity inside a spherical conductor as shown. Another point charge Q is placed outside the conductor as shown. Now as the point charge Q is pushed away from conductor, the potential difference (V_(A) - V_(B)) between two points A and B within the cavity of sphere remains constant. Reason: The electric field due to charges on outer surface of conductor and outside the conductor is zero at all points inside teh conductor.

A spherical conductor A contains two spherical cavities as shown in Fig.2.127. The total charge on conductor itself is zero . However , there is a point charge q_(1) at the center of one cavity and q_(2) at the center of the other cavity . Another charge q_(3) is placed at a large distance r from the center of the spherical conductor. If q_(1) is displaced from its center slightly (being always inside the same cavity ), then the correct representation of field lines inside the same cavity is

The figure shows a charge q placed inside a cavity in an uncharged conductor. Now if an external electric field is swiched on

the figure shows a charge q placed inside a cavity in an uncharged conductor, Now if na external electric field is switched on

A point charge q_1 is placed inside cavity 1 and another point charge q_2 is inside cavity 2. A point charge q is placed outside the conductor. For the situation described above, answer the following questions. The charge on outer surface of the conductor would be
