Coulomb's Law

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the force between two charged objects, stating that the force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance between them.

What is the formula for Coulomb's Law?

Back

F = k * |q1 * q2| / r^2, where F is the force between the charges, k is Coulomb's constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.

What is the standard unit of electric charge?

Back

Coulombs (C) is the standard unit of electric charge.

What happens to the force between two charges if the distance between them is doubled?

Back

The force between the charges decreases by a factor of four, as it is inversely proportional to the square of the distance.
