NEET Physics Electric Dipole MCQ Question
Which of the following statements about an electric dipole is correct?
The dipole moment vector points from the negative charge to the positive charge.
The magnitude of the dipole moment is given by the formula p = q × d, where d is the distance between charges.
The dipole moment is always equal to zero for a system of two equal and opposite charges.
The dipole moment is directed along the dipole axis from -q to q.
Correct Answer
Detailed Explanation
The dipole moment vector p is defined to be in the direction of the dipole axis from -q to q, and its magnitude is given as 2qa according to the NCERT context.
