Question:
(a) A spherical capacitor consists of two concentric conducting spheres of radii \(R\) and \(2 R\). If the two spheres carry charges of \(+q\) and \(-q\), what is the average energy density inside the capacitor in terms of \(R\) and \(q\) ?
(b) \(\mathrm{A}\) cylindrical capacitor of length \(\ell\) consists of two coaxial conducting cylinders of radii \(R\) and \(2 R\). If the two cylinders carry charges of \(+q\) and \(-q\), what is the average energy density inside the capacitor?
