A point charge q produces an electric field of magnitude 2.0 NC^(-1) at a point distant 50 cm from it. From the value of q.

A small positively charged ball of mass m is suspended by an insulating thread of length L. This ball remains in equilibrium with string horizontal when another small charged ball is placed exactly at a distance L below the point of suspension of the first ball. The second ball is slowly moved away from the first ball to a far away point. (The second ball is moved horizontally so that the first ball does not accelerate). As a result the first ball lowers down to the original position of the second ball and the string become vertical. Find the work done by the external agent in removing the second ball.

A point charge q is placed at the origin . How does the electric field due to the charge very with distance r from the origin ?

A point charge q produces an electric field of magnitude 2NC^(-1) at a point distance 0.25 m from it. What is the value of charge ?

Inside a hollow conducting sphere, which is uncharged, a charge q is placed at its center. Let electric field at a distance x from center at point p be E and potential at this point be V. Now, some positive charge Q is given to this sphere, then
