For an electric field that increases in magnitude along the $x$-direction,what is the nature of the equipotential surfaces?

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

The figure shows two equipotential lines in the $XY$ plane for an electric field. The scale is shown. The $X$-component $E_x$ and $Y$-component $E_y$ of the electric field in the space between the equipotential lines are respectively:

$A$ 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?

The work done to move a charge on an equipotential surface is

$A$ uniform electric field pointing in the positive $x$-direction exists in a region. Let $A$ be the origin,$B$ be the point on the $x$-axis at $x = +1 \, cm$,and $C$ be the point on the $y$-axis at $y = +1 \, cm$. Then the potentials at the points $A$,$B$,and $C$ satisfy
