Given below are two statements:
Statement I An electric diploe is placed at the centre of a hollow sphere. The flux of electric field through the sphere is zero but the electric field is not zero anywhere in the sphere.
Statement II If is the radius of a solid metallic sphere and be the total charge on it. The electric field at any point on the spherical surface of radius is zero but the electric flux passing through this closed spherical surface of radius is not zero.
In the light of the above statements, choose the correct answer from the options given below.

In the light of the above statements, choose the correct answer from the options given below.
View answer and explanation
Correct option: B
Statement I is true but Statement II is false.
Option B is correct because Statement I is true (flux through the sphere is zero due to the dipole's net charge being zero), but Statement II is false (electric field inside a charged solid sphere is non-zero).
