Question:

Which of the following statements are correct ?

(A) Electrostatic field lines form closed loops.
(B) In an electric dipole, the direction from charge to q is the direction of the dipole.
(C) Water molecule is an example of polar molecule.
(D) The electric field due to a uniformly charged thin shell is zero at some points inside the shell.
(E) Electrostatic force is conservative in nature.

Choose the correct answer from the options given below:

Options:

(A) and (D) only

(A), (B) and (D) only

(B), (C) and (E) only

(C), (D) and (E) only

Correct Answer:

(B), (C) and (E) only

Explanation:

The correct answer is Option (3) → (B), (C) and (E) only

(C) Water $H_2O$ is a polar molecule because it has a permanent electric dipole moment due to its bent structure and unequal distribution of charge.

(D) The electric field inside a uniformly charged thin shell is zero at all points, as per Gauss's law.

(E) Electrostatic force is conservative in nature because the work done by the force depends only on the initial and final positions of the charge and not on the path taken.
