Coulomb's Law Quick Check

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 decreases to one-fourth of its original value.

Front

If the charge of one object is doubled, how does it affect the electrostatic force?

Back

The electrostatic force doubles.

Front

How does the sign of the charges affect the force between them?

Back

Like charges repel each other, while opposite charges attract each other.
