The surface density on the copper sphere is . The electric field strength on the surface of the sphere is
1
2
3
4
Explanation:
Since on decreasing the distance between the two charges, and on decreasing angle between the dipole and electric field, sin decreases therefore torque decreases.

A thin metallic spherical shell contains a charge on it. A point charge is placed at the centre of the shell and another charge is placed outside it as shown in the figure. All the three charges are positive. The Force on the charge at the centre is
1 towards left
2 towards right
3 upward
4 Zero
Explanation:
Electric field inside the metallic shell is zero. Electric force on the charge at the centre of metallic shell is zero.
