Question:

Select the correct statement from the following

A. Gauss’s law is true for any closed surface, no matter what its shape or size.

B. If the net electric flux through a closed surface is zero, we can conclude that the total charge contained in the closed surface is also zero.

C. Gauss’s law is not based on the inverse square dependence on distance contained in the coulomb’s law.

D. The electric field due to a charge outside the Gaussian surface contributes zero net flux through the surface.

Choose the correct answer from the options given below

Options:

A only

A and C only

A, B and D only

B, C and D only

Correct Answer:

A, B and D only

Explanation:

The correct answer is option (3) : A, B and D only

Gauss law is true for any closed surface, no matter what its shape or size is. If net electric flux through a closed surface is zero then total charge enclosed by the closed surface would also be zero.

The contribution of the charges outside the closed surface in producing the flux is zero. Gauss’s law is based on the inverse square dependence on distance contained in coulomb’s

Hence statement C is wrong and A, B and D is correct.
