FAQs on L 2 Electric field (Electrostatics ) - Dipole moment , Physics Video Lecture - Additional Study Material for NEET

1. What is the definition of dipole moment in electrostatics?
Ans. Dipole moment is a measure of the separation of positive and negative charges in a system. It is defined as the product of the magnitude of either charge and the distance between them.
2. How is the dipole moment calculated in a system?
Ans. The dipole moment of a system can be calculated by multiplying the magnitude of the charge on either end of the dipole by the distance between them. The formula is given by p = q * d, where p is the dipole moment, q is the magnitude of the charge, and d is the distance between the charges.
3. What is the significance of dipole moment in physics?
Ans. The dipole moment is an important concept in physics as it helps in understanding the behavior of electric fields and interactions between charges. It is particularly useful in studying the behavior of polar molecules, the polarization of materials, and the interactions between atoms or molecules.
4. How does the dipole moment affect the electric field around a system?
Ans. The dipole moment affects the electric field by creating a non-uniform distribution of charges. The electric field lines around a dipole are not symmetrical but instead point towards the negative charge and away from the positive charge. This asymmetry in the electric field is a result of the dipole moment and influences the interactions between charges in the system.
5. Can the dipole moment of a system be zero?
Ans. Yes, the dipole moment of a system can be zero if the separation between the positive and negative charges is zero or if the magnitudes of the charges are equal. In such cases, the charges cancel each other out, resulting in a net dipole moment of zero.
