Question no.2.30- A spherical capacitor has an inner sphere of radius 12 cm and an outer sphere of radius 13 cm. The outer sphere is earthed and the inner sphere is given a charge of 2.5 muC`. The space between the concentric spheres is filled with a liquid of dielectric constant 32. (a)- Determine the capacitance of the capacitor. (b)- What is the potential of the inner sphere ? (c)- Compare the capacitance of this capacitor with that of an isolated sphere of radius 12 cm. Explain why the later is much smaller ?
