Identify the incorrect statements among the following.

(A) The two charges of an electric dipole will experience force in the same direction when placed in a uniform electric field,
(B) The dipole moment is a vector quantity,
(C) The direction of the dipole moment is from +q charge towards -q charge,
(D) The torque acting on the dipole in an electric field depends on the intensity of the field and the dipole moment.

Choose the correct answer from the options given below:

(A) and (C) only

The correct answer is Option (4) → (A) and (C) only

Explanation:

(A) In a uniform electric field, both charges of the dipole experience equal and opposite forces that form a couple, producing a torque but no net force. Hence, this statement is incorrect.

(B) The dipole moment is defined as $ \vec{p} = q \times 2\vec{a} $ and has both magnitude and direction. Hence, it is a vector quantity. This statement is correct.

(C) The direction of dipole moment is conventionally taken from −q to +q. Hence, this statement is incorrect.

(D) The torque on an electric dipole is given by

$ \tau = pE\sin\theta $

Incorrect statements: (A) and (C)
