FAQs on Vector form of Coulomb's Law Video Lecture - Physics Class 12 - NEET

1. What is the vector form of Coulomb's Law?
Ans. The vector form of Coulomb's Law is given by the equation F = k(q1q2/r^2) * r̂, where F is the electrostatic force between two charged particles, k is the electrostatic constant, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and r̂ is the unit vector pointing from one charge to the other.
2. How is Coulomb's Law represented in vector notation?
Ans. Coulomb's Law is represented in vector notation by using the unit vector r̂, which indicates the direction of the force between two charged particles. The magnitude of the force is calculated using the formula F = k(q1q2/r^2) and then multiplied by the unit vector r̂ to obtain the vector form of the equation.
3. What does the unit vector r̂ represent in Coulomb's Law?
Ans. The unit vector r̂ in Coulomb's Law represents the direction of the force between two charged particles. It points from the location of the first charge towards the location of the second charge. Multiplying the magnitude of the force by the unit vector r̂ gives the vector form of Coulomb's Law, which includes both the magnitude and direction of the force.
4. How does the distance between two charges affect the electrostatic force according to Coulomb's Law?
Ans. According to Coulomb's Law, the electrostatic force between two charges is inversely proportional to the square of the distance between them. As the distance between the charges increases, the force decreases. Conversely, if the distance decreases, the force increases. This relationship shows that the force weakens as the charges move farther apart and strengthens as they move closer together.
5. What is the significance of the electrostatic constant (k) in Coulomb's Law?
Ans. The electrostatic constant (k) in Coulomb's Law is a proportionality constant that relates the magnitude of the charges and the distance between them to the electrostatic force. Its value is approximately 8.99 x 10^9 Nm^2/C^2. The constant ensures that the units of force in Coulomb's Law are in Newtons (N) and that the equation accurately describes the relationship between charges and forces.
