A spherical conductor of diameter 6 mm is kept in uniform electric field of intensity N/C. The maximum charge on the conductor is

Answer: (D)

Solution

The maximum charge a conductor can hold is limited by the field at its surface reaching the given limiting value N/C. For a charged sphere of radius , the surface field is . Radius mm $=
