The space between two concentric conducting spherical shells ofradii b = 1.70 cm and a =1.20 cm is filled with a substance of dielectric constant κ = 29.5. A potentialdifference V = 65.5 V is applied across the inner and outershells.
(a) Determine the capacitance of the device.
nF
(b) Determine the free charge q on the innershell.
nC
(c) Determine the charge q' induced along the surfaceof the inner shell.
