B M Sharma Solutions for Chapter: Electric Potential, Exercise 3: DPP

Two metal spheres, one of radius $R$ and the other of radius $2R$, both have same surface charge density $\sigma$. They are brought in contact and separated. What will be new surface charge densities on them?

Two charges $q_1$ and $q_2$ are placed at $\left(0,0,d\right)$ and $\left(0,0,-d\right)$ respectively. Find the locus of points where the potential is zero.

Equipotentials at a great distance from a collection of charges, whose total sum is not zero, are approximately

Figure shows some equipotential lines distributed in space. A charged object is moved from point $A$ to point $B$

In the electric field of a point charge $q$ which is located at center of sphere as shown, a certain charge is carried from point $A$ to $B, C, D$ and $E$. Then work done by external agent

Equipotential surfaces are shown in the following figure. Then the electric field strength will be

A closed equipotential surface with no charge within itself must enclose an equipotential volume.

If an insulated, uncharged conductor is placed near a charged conductor and no other conductors are present, the uncharged body must intermediate in potential between that of the charged body and that of infinity.
