Coulomb's Law

Front

What is Coulomb's Law?

Back

Coulomb's Law states that the force between two charged objects 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 force if the distance between two charges is halved?

Back

The force quadruples.

Front

What do 'Newtons' represent in physics?

Back

Newtons represent force.

Front

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

Back

The force is reduced by 1/4.

Front

What two factors does Coulomb's Law depend on?

Back

Coulomb's Law depends on the size of the charges and the distance between them.

Front

If each of the charges is doubled, what happens to the force?

Back

The force quadruples.

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 (k) is approximately 8.99 x 10^9 N m²/C².

Front

How does the force change if one charge is tripled?

Back

The force triples.

Front

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

Back

The force is inversely proportional to the square of the distance between the charges.
