The variation of potential with distance x from a fixed point is shown in figure. The electric field at

List $\mathrm{I}$ gives certain situations in which electric field is represented by electric lines of forces in $x-y$ plane. List $\mathrm{II}$ gives corresponding representation of equipotential lines in $x-y$ plane. Match the figures in List $\mathrm{I}$ with the figures in List $\mathrm{II}$ and indicate your answer.

In the electric field of charge $Q$, another charge is carried from $A$ to $B$, $A$ to $C,A$ to $D$ and $A$ to $E$, then work done will be:

As shown in figure, on bringing a charge $Q$ from point $A$ to $B$ and from $B$ to $C$, the work done are $2$ joules and - $3$ joules respectively. The work done bringing the charge from $C$ to $A$ will be
