Coulomb's Law
Electrostatic force between two point charges q1, q2 distance r apart is proportional to:
Select the correct option:
Solution
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).
