There is a uniform electric field of intensity $E$ as shown in the figure. How many labelled points have the same electric potential as the fully shaded point?

Which of the following statements is $NOT$ $TRUE$?

The figure shows three points $A$,$B$,and $C$ in a region of uniform electric field $\overrightarrow{E}$. The line $AB$ is perpendicular and $BC$ is parallel to the field lines. Which of the following relations holds good? Let $V_A$,$V_B$,and $V_C$ represent the electric potential at points $A$,$B$,and $C$ respectively.

In the figure,the charge $Q$ is at the centre of the circle. Work done is maximum when another charge is taken from point $P$ to:

$A$ 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

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.
