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 is shown in the diagram, what is its correct direction?
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 has a magnitude of 2qa and is directed from -q to +q along the dipole axis, as mentioned in the NCERT context.
