Distinguish between electric field and electrostatic potential.

(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.
