Electric Charges and Fields

Question:

Which of the following are true statements?

(A) Electric field due to a single charge is cylindrically symmetric.
(B) Gauss's theorem holds good for any closed surface.
(C) Electric field due to an electric dipole is spherically symmetric
(D) The field due to a uniformly charged spherical shell is zero at all points inside the shell.

Choose the correct answer from the options given below:

Options:

(A) and (B) only

(B) and (C) only

(C) and (D) only

(B) and (D) only

Correct Answer:

(B) and (D) only

Explanation:

The correct answer is Option (4) → (B) and (D) only

(B) Gauss Theorem states that the electric flux through a closed surface is proportional to the charge enclosed in the surface.

(D) For a spherical cell with uniform charge, the electric field inside the shell is zero at all points. This happens because the contributions of each part of the spherical cell cancel out due to symmetry.
