Equipotential surfaces associated with an electric field which is increasing in magnitude along the $x$-direction are

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

The angle between the electric lines of force and the equipotential surface is (in $^{\circ}$)

$A$ uniform electric field exists in the plane of the paper as shown. Here $A, B, C$, and $D$ are points on the circle. $V_{A}, V_{B}, V_{C}$, and $V_{D}$ are the potentials at those points respectively. Then:

Draw an equipotential surface for a point charge.

$A$ uniform electric field is directed along the $Y$-axis. Consider point $A$ as the origin $(0,0) \text{ m}$. The coordinates of point $B$ are $(0,2) \text{ m}$. The coordinates of point $C$ are $(2,0) \text{ m}$. If the electric potentials at points $A, B,$ and $C$ are $V_A, V_B,$ and $V_C$ respectively,which of the following options is correct?
