Question

By what Factor The capacitance of a metal sphere increases if its volume is made 27 times????
Anyone explain....

Answer 1

The capacitance of a metal sphere is given by C=E A/d so C is proportional ... Since the volume is increased 27 times, that implies 3×3×3 =27 so it ... The volume of a sphere varies directly as the cube of its radius and its volume is 365pi cm3. What is the volume of the sphere when the diameter is doubled?
