NEET Physics Electric Dipole MCQ Question

Type: MCQ-diagram based-Medium-Class 12

Consider a diagram showing an electric dipole consisting of two charges +q and -q separated by a distance 2a along the horizontal axis. If the dipole moment vector p\mathbf{p} is shown in the diagram, what is its correct direction?

Question diagram
A

From -q to +q along the dipole axis

B

From +q to -q along the dipole axis

C

Perpendicular to the dipole axis

D

Parallel to the line joining the charges but outside the dipole

Correct Answer

Option A

Detailed Explanation

The dipole moment vector p\mathbf{p} has a magnitude of 2qa and is directed from -q to +q along the dipole axis, as mentioned in the NCERT context.
