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 if the distance between two charges is halved?

Back

The electrostatic force increases by a factor of four (quadruples).

Front

What is the formula for calculating the electrostatic force between two charges?

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

If the charge of one particle is doubled, what happens to the force?

Back

The force also doubles.

Front

What type of charges attract each other?

Back

Opposite charges (positive and negative) attract each other.

Front

What type of charges repel each other?

Back

Like charges (positive-positive or negative-negative) repel each other.

Front

How does the electrostatic force change with distance?

Back

The electrostatic force decreases as the distance between the charges increases; this relationship is inversely proportional.

Front

If two charges of 1.0 C each are 1.0 meter apart, what is the magnitude of the force between them?

Back

9E9 N.

Front

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

Back

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