## FAQs on Detailed Explanation: Coulomb's Law Video Lecture - Physics Class 12 - NEET

 1. What is Coulomb's Law? Ans. Coulomb's Law is a fundamental principle in physics that describes the electrostatic interaction between charged particles. It states that the force between two charged objects is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
 2. How is Coulomb's Law mathematically expressed? Ans. Coulomb's Law is mathematically expressed as F = k * (q1 * q2) / r^2, where F is the electrostatic force between the charges q1 and q2, r is the distance between them, and k is the electrostatic constant.
 3. What does the inverse square relationship in Coulomb's Law mean? Ans. The inverse square relationship in Coulomb's Law means that as the distance between two charged objects doubles, the electrostatic force between them decreases by a factor of four. Similarly, if the distance is halved, the force increases by a factor of four.
 4. How does Coulomb's Law apply to everyday life? Ans. Coulomb's Law applies to various aspects of everyday life. For example, it explains the attraction and repulsion between charged particles, which is fundamental to the functioning of electronic devices like smartphones and computers. It also helps understand phenomena such as static electricity, lightning, and the behavior of charged particles in electric fields.
 5. How does Coulomb's Law relate to the concept of electric field? Ans. Coulomb's Law is closely related to the concept of electric field. The electric field is a region around a charged object where another charged object experiences a force. The strength of the electric field is determined by the charge of the object creating it, and the direction of the field is determined by the sign of the charge. Coulomb's Law can be used to calculate the electric field strength at a point in space.
