An isolated solid metal sphere of radius `R` is given an electric charge. The variation of the intensity of the electric field with the distance `r` from the centre of the sphere is best shown by

A conducting sphere of radius R is given a charge Q . The electric potential and the electric field at the centre of the sphere respectively are

A conducting sphere of radius R is charged to a potential of V volts. Then the electric field at a distance r ( gt R) from the centre of the sphere would be

A non-conducting solid sphere of radius R is uniformly charged. The magnitude of the electric filed due to the sphere at a distance r from its centre

An isolated solid metallic sphere is given +Q charge. The charge will be distributed on the sphere

A sphere of radius R, is charged uniformly with total charge Q. Then correct statement for electric field is (r = distance from centre): -

An isolated non-conducting solid sphere of radius R is given an electric charge. The charge is uniformly distributed in the volume of sphere. The graph which shows the correct variation of magnitude of electric field with distance from the centre of the sphere is
