FAQs on Coulomb's Law Video Lecture - Basic Physics for IIT JAM
| 1. What is Coulomb's Law? |  |
Ans. Coulomb's Law is a fundamental law in physics that describes the electrostatic interaction between charged particles. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
| 2. How can Coulomb's Law be mathematically expressed? | |
Ans. Coulomb's Law can be mathematically expressed as F = k * (q1 * q2) / r^2, where F is the electrostatic force between the particles, k is the electrostatic constant, q1 and q2 are the charges of the particles, and r is the distance between them.
| 3. What is the significance of the electrostatic constant (k) in Coulomb's Law? | |
Ans. The electrostatic constant (k) in Coulomb's Law determines the strength of the electrostatic force between two charged particles. It is a proportionality constant that depends on the medium in which the charged particles are located. In a vacuum, the value of k is approximately 9 × 10^9 N m^2/C^2.
| 4. How does Coulomb's Law explain the behavior of charged particles? | |
Ans. Coulomb's Law explains that like charges repel each other, while opposite charges attract each other. The force between charged particles decreases as the distance between them increases. This law helps us understand the behavior of charged particles and how they interact in various electrostatic situations.
| 5. Can Coulomb's Law be used to calculate the force between more than two charged particles? | |
Ans. Yes, Coulomb's Law can be extended to calculate the force between more than two charged particles. The force on a particular charged particle due to multiple charges can be found by applying Coulomb's Law separately for each pair of charges and then vector summing the individual forces to obtain the net force acting on the particle.
