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

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 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

For a uniformly charged non conducting sphere of radius R which of following shows a correct graph between the electric field intensity and the distance from the centre of sphere –

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 conducting shell of radius R carries charge -Q . A point charge +Q is placed at the centre. The electric field E varies with distance r (from the centre of the shell) as

A sphere of radius R carries charge such that its volume charge density is proportional to the square of the distance from the centre. What is the ratio of the magnitude of the electric field at a distance 2 R from the centre to the magnitude of the electric field at a distance of R//2 from the centre?

A hallow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre:
