(N/A) The electric field $E$ of a point charge $Q$ at a distance $r$ is given by $E = \frac{kQ}{r^2}$.
The electrostatic potential $V$ of a point charge $Q$ at a distance $r$ is given by $V = \frac{kQ}{r}$.
Comparing the two expressions,we can see that $V = E \times r$.
Key differences:
$1$. Electric field is a vector quantity,whereas electrostatic potential is a scalar quantity.
$2$. The electric field represents the force per unit charge,while the electrostatic potential represents the work done per unit charge in bringing a test charge from infinity to a point.

Find the potential $V$ of an electrostatic field $\vec{E} = a(y\hat{i} + x\hat{j})$,where $a$ is a constant.

In space,the electric potential varies as $V = 20|\vec{r}|$ volt,where $\vec{r} = x \hat{i} + y \hat{j} + z \hat{k}$ is the position vector. Then,the electric field in $N C^{-1}$ at the point $(4 \ m, 3 \ m, -5 \ m)$ is:

In a region,the electric field is $(30 \hat{i} + 40 \hat{j}) \text{ NC}^{-1}$. If the electric potential at the origin is zero,the electric potential at the point $(1 \text{ m}, 2 \text{ m})$ is

Assume that an electric field $\overrightarrow{E} = 30x^2 \hat{i}$ exists in space. Then the potential difference $V_A - V_O$,where $V_O$ is the potential at the origin and $V_A$ is the potential at $x = 2 \, m$,is: (in $, V$)
