Coloumbs law Quiz Practice Quiz | Coulomb's Law

Q: What is the unit of charge in the SI system?

Coulomb (C) — Charge is measured in Coulombs, the fundamental unit.

Q: Coulomb's Law describes the force between which of the following?

Electric charges — Coulomb's Law specifically deals with the electrostatic force.

Q: If the distance between two charges is doubled, the electrostatic force between them becomes:

One-fourth as strong — The force is inversely proportional to the square of the distance (1/r^2).

Q: According to Coulomb's Law, the force between two charges is:

Directly proportional to the product of the charges and inversely proportional to the square of the distance. — F = k * q1 * q2 / r^2 describes the relation.

Q: What is the value of the electrostatic constant (k) in Coulomb's Law (approximately)?

9 x 10^9 N?m²/C² — The value of k (Coulomb's constant) is a fundamental constant used in the equation.
