An isolated conducting sphere of radius r1 = 0.20 m is at a potential of -2000V, with charge Qo. The charged sphere is then surrounded by an uncharged conducting sphere of inner radius r2 = 0.40 m, and outer radius r3 = 0.50m, creating a spherical capacitor.
(a)Draw a clear physics diagram of the problem.
(b) Determine the charge Qo on the sphere while its isolated.
(c)A wire is connected from the outer sphere to ground, and then removed. Determine
the magnitude of the electric field in the following regions:
R<r1 ; re<R < r2; r2< R < r3; r3 < R
(d) Determine the magnitude of the potential difference between the sphere and the
conducting shell.
(e) Determine the capacitance of the spherical capacitor.
