# Charged Sphere and its own energy.

**Electricity and Magnetism**Level 3

Find the self energy of a uniformly charged sphere of charge \(q_0\) and radius \(R\).

**Details and assumptions:**

\(q_0 = \frac{10^{-5}}{3} C\)

\(R = 0.01 m\)

\(\frac{1}{4\pi \epsilon_{0}} = 9 \times 10^{9} S . I units\)
