The space between two concentric conducting spherical shells of radii b = 1.80 cm and a = 1.10 cm is filled with a substance of dielectric constant k = 18.8. A potential difference V = 97.0 V is applied across the inner and outer shells. Determine (a) the capacitance of the device, (b) the free charge q on the inner shell, and (c) the charge q induced along the surface of the inner shell. (a) Number Units (b) Number Units (c) Number Units
