A hollow spherical conductor of radius R is given a charge Q. Work done in moving a charge q from its centre to surface is:

Equal charges are given to two spheres of different radii. The potential will:

be more on smaller sphere

be more on bigger sphere

be equal on both the spheres

depend on the nature of the materials of the spheres.

Three small spheres each having a charge +q are placed on the circumference of a circle such that they form an equilateral triangle. Pick out the correct statement.

Which of the following is not the property of equipotential surfaces ?

They do not cross each other.

They are concentric spheres for non-uniform electric field.

Rate of change of pential with the distance on them is zero.

They can be imaginary spheres.

160 MW

20 MW

400 MW

60 MW

Equipotential surfaces associated with an electric field which is increasing in magnitude along x direction are:

planes parallel to yz plane

planes parallel to xy plane

planes parallel to rz plane

coaxial cylinders of increasing radii around x-axis.

Four equal charges, each of charge, Q are placed at the four corners of a body of side a each. Work done to remove a charge-Q from the centre of the body to infinity is:
