Figure below shows the variation of electrostatic potential $V$ with distance $\text{'}x\text{'}$ for a given charge distribution. From the points marked $A, B$ and $C$, identically the point at which the electric field is maximum. Explain your answer.

Two identical plane metallic surfaces $A$ and $B$ are kept parallel to each other in air, separated by a distance of $1 \mathrm{cm}$, as shown in figure below.

Surface $A$ is given a positive potential of $10 V$, and the outer surface of $B$ is earthed.

What is the magnitude and direction of the uniform electric field between points $Y$ and $Z$?

What is the work done in moving a charge of $20 \mu C$ from point $X$ to point $Y$.

The electric potential as a function of distance $x$ is shown in Figure below. Construct a graph of the electric field strength $E$.

The two graphs drawn here, show the variation of electrostatic potential $\left(V\right)$ with $\frac{1}{r}$($r$ being distance of the field point charge) for two point charges $q_1$ and $q_2$. What are the signs of the two charges?

The following data was obtained for the dependence of the magnitude of electric field, with distance, from a reference point $O$, within the charge distribution in the shaded region.

Identify the charge distribution and justify your answer.

The following data was obtained for the dependence of the magnitude of electric field, with distance, from a reference point $O$, within the charge distribution in the shaded region.

If the potential due to this charge distribution, has a value $V$ at the point $A$, what is its value at the point $A\text{'}$?
