Odisha Board Solutions for Chapter: Electric Field and Potential, Exercise 1: MODEL QUESTIONS

The relation between electric potential and electric field strength is $E_l=$ _____ $\times \raisebox{1ex}{$dV$}\!\left/ \!\raisebox{-1ex}{$dl$}\right.$. (Enter an integer in the blank).

The electric field strength at a point due to an isolated charge varies inversely as the cube of its distance from the point.

Electric field is a scalar quantity.

The S.I unit of electric field strength is $\mathrm{N}/{\mathrm{C}}^2$.

Electric field intensity at a point is equal to the potential gradient at that point.

Two electric lines of force cross each other at a suitable point.

Equipotential lines and the lines of force intersect at $60°$ at each other.

Two different equipotential lines intersect each other at a suitable point.
