Vedclass · Answer

(B) The electrostatic energy density $u$ is defined as the energy stored per unit volume in an electric field.The formula for electrostatic energy density is given by $u = \frac{dU}{dV} = \frac{1}{2} \epsilon_0 E^2$,where $\epsilon_0$ is the permittivity of free space and $E$ is the electric field intensity.From this expression,it is clear that the electrostatic energy density is directly proportional to the square of the electric field intensity,i.e.,$u \propto E^2$.

If $E$ is the electric field intensity of an electrostatic field,then the electrostatic energy density is proportional to
