The space between two concentric conducting spherical shells ofradii b = 1.70 cm and a = 1.20 cm is filled witha substance of dielectric constant κ = 19.0. A potential difference V =62.0 V is applied across the inner andouter shells.
(a) Determine the capacitance of the device.
nF
(b) Determine the free charge q on the inner shell.
nC
(c) Determine the charge q' induced along the surface ofthe inner shell.
