Coulomb's Law

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the electrostatic 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.

Front

What happens to the electrostatic force when the distance between two charges is doubled?

Back

The electrostatic force is cut by 1/4.

Front

What are the units of the variable 'r' in Coulomb's Law?

Back

Meters.

Front

What does F_e represent in Coulomb's Law?

Back

The electrostatic force.

Front

How does the electrostatic force change when the distance increases?

Back

The electrostatic force decreases.

Front

If one of the charges in Coulomb's Law doubles, what happens to the force?

Back

The force doubles.

Front

What is the formula for Coulomb's Law?

Back

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

Front

What is Coulomb's constant (k)?

Back

Coulomb's constant is approximately 8.99 x 10^9 N m²/C².

Front

What is the relationship between charge and force in Coulomb's Law?

Back

The electrostatic force is directly proportional to the product of the charges.

Front

What happens to the force if both charges are doubled?

Back

The force quadruples.
