A spherical capacitor has inner radius of a = 2 cm and outer radius of b =

Question:

A spherical capacitor has inner radius of a = 2 cm and outer radius of b = 4 cm. The interior is a dielectric material with ε_oε_r. The outer conductor is grounded while the inner one is maintained at 100 V.

(a) Determine ε_r if the surface charge density on the inner conductor is 400 nC/m².

(b) Find the capacitance of the structure.
