Solution
Correct Answer:
q1q2/r2
Coulomb's Law describes the fundamental force between stationary electric charges.
- The magnitude of the force (F) is directly proportional to the product of the magnitudes of the charges (q1q2).
- It is inversely proportional to the square of the distance (r) between them. F=kr2q1q2 where k is Coulomb's constant (k=4πϵ01≈9×109 Nm2/C2).
This easy difficulty physics question is from the chapter electrostatics, covering the topic of coulomb's law. It appeared in the 2025 exam.
