A \(1~\mbox{nC}\) charge is placed inside a grounded conducting hollow sphere of radius \(10~\mbox{cm}\) centered on the origin. If the charge is placed at \((5~\mbox{cm},0,0)\), what is the electric potential at \((-5~\mbox{cm},0,0)\)?
Details and assumptions
- Let \(1/4 \pi \epsilon_0=K=9\times 10^9 ~\mbox{Nm}^2/\mbox{C}^2\).
