NEET Physics Electric Dipole MCQ Question
A diagram shows an electric dipole consisting of two charges, +q and -q, separated by a distance of 2a. The dipole moment vector p is shown pointing from -q to +q along the dipole axis. Which of the following correctly describes the magnitude of the dipole moment?
The dipole moment has a magnitude of 2qa.
The dipole moment has a magnitude of qa^2.
The dipole moment has a magnitude of q/2a.
The dipole moment has a magnitude of q^2a.
Correct Answer
Detailed Explanation
The dipole moment of an electric dipole is defined as the product of the charge and the separation distance between the charges. Thus, the magnitude of the dipole moment is 2qa as per the given context.
