The work done in carrying a charge $\mathrm{q}$ once round a circle of radius $\mathrm{a}$ with a charge $\mathrm{Q}$ at it's centre is:

The points resembling equal potentials are

What is not true for equipotential surface for uniform electric field?

Mark the correct statement :

The figure shows three points $A\mathit{,} B$ and $C$ in a region of uniform electric field $\overrightarrow{\mathrm{E}}$. The line $AB$ is perpendicular and $BC$ is parallel to the field lines. Then, which of the following holds good?


 

($V_{\mathit{A}}\mathit{,}\mathit{ }{V}_{\mathit{B}}$ and $V_{\mathit{c}}$ represent the electric potentials at the points $A, B$ and $C$, respectively.)

Correct statement is

Electric lines of force are as shown in the figure. Then the potential at point $P$
