Can a metal sphere of radius 1 cm hold a charge of 1 C?

Assertion: A metal sphere of radius 1 cm can not hold a charge of 1 coulomb Reason: For placing a charge of 1 coulomb on a shere of radius 1 cm, its potential has to eb raised to = 9 xx 10^22 V

A metal of radius of 1 cm can not hold a charge of 1 coulomb. Why?

A hollow metal sphere of radius 5 cm is charged, such that the potential on its surfae is 10 V. The potential at the centre of the sphere is

A hollow metallic sphere of radius 10 cm is charged, such that potential of its surface is 70 V. The potential at the centre of the sphere would be

A solid metal sphere of radius r has charge +Q. This charge is one the surface of the sphere but it may be considered to be a point charge at its centre. The sphere has radius 36 cm. Determine, for this sphere the capaciance the charge requried to raise the potential of the sphere form zero to 7.0 xx 10^5V .

A spherical capacitor has an inner sphere of radius 10 cm and outer sphere of radius 12 cm . The outer sphere is earthed and the inner sphere is given a charge of 5 mu C . Find its capacitance.

A solid metal sphere of radius r has charge +Q. This charge is one the surface of the sphere but it may be considered to be a point charge at its centre. Suggest, why your calculation in (a) for the metal sphere would not apply to a plastic sphere.

A conducting sphere of radius 10 cm has an unknown charge. If the electric field 20 cm from the centre of the sphere is 1.5xx 10^3N//C and points radially inward, what is the net charge on the sphere?
