Surround Ground

Electricity and Magnetism Level 3

A 1 nC1~\mbox{nC} charge is placed inside a grounded conducting hollow sphere of radius 10 cm10~\mbox{cm} centered on the origin. If the charge is placed at (5 cm,0,0)(5~\mbox{cm},0,0), what is the electric potential at (−5 cm,0,0)(-5~\mbox{cm},0,0)?

Details and assumptions

  • Let 1/4πϵ0=K=9×109 Nm2/C21/4 \pi \epsilon_0=K=9\times 10^9 ~\mbox{Nm}^2/\mbox{C}^2.
