A spherical capacitor has an inner sphere of radius 12cm and n outer sphere of radius 13 cm. The outer sphere is earthed and the inner sphere is given a charge of `2.5muC`. The space between the concentric spheres is filled with a liquid of dielectric constant 32.
Determine the capacitance of the capacitor

A spherical capacitor has an inner sphere of radius 12cm and n outer sphere of radius 13 cm. The outer sphere is earthed and the inner sphere is given a charge of 2.5muC . The space between the concentric spheres is filled with a liquid of dielectric constant 32. Compare the capacitance of this capacitor with that of an isolated sphere of radius 12 cm. Explain why the latter is much smaller
