Vedclass · Answer

(C) The electric potential $V$ at a distance $r$ from a point charge $q$ is given by $V = \frac{kq}{r}$.Since points $A, B, C, D$ and $E$ all lie on the circumference of a circle centered at the point charge $q$,they are all at the same distance $r$ from the charge.Therefore,all these points are at the same electric potential,making the path $ABCDE$ an equipotential surface.By definition,the work done $W$ in moving a charge $q_0$ between two points at the same potential is $W = q_0(V_f - V_i) = q_0(V - V) = 0$.Thus,the work done in moving a charge from point $A$ to any of the points $B, C, D$ or $E$ is zero.

In the electric field of a point charge $q$,a certain charge is carried from point $A$ to points $B, C, D$ and $E$ as shown in the figure. Then the work done:

$A$ charge is moved from point $A$ to points $B, C, D,$ and $E$ in the electric field of a charge $Q$ placed at the center of a circle. The work done will be:

Work done in moving a positive charge on an equipotential surface is

There is $10$ units of charge at the centre of a circle of radius $10\,m$. The work done in moving $1\,unit$ of charge around the circle once is...........$units$.

Assertion $(A)$: In a region of constant potential,the electric field is zero and there can be no charge inside the region.
Reason $(R)$: According to Gauss's law,the charge inside the region should be zero if the electric field is zero.
