A charge Q is filled in a spherical volume of Radius R . Use the concept of energy density , find energy stored inside the charge volume.

Explanation

To find the energy stored inside a spherical volume of radius \( R \) filled with a charge \( Q \), we will use the concept of energy density in electrostatics. The energy density \( u \) is given by the formula:

\[ u = \frac{1}{2} \epsilon_0 E^2 \]

where \( \epsilon_0 \) is the permittivity of free space and \( E \) is the electric field.
