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

How does distance affect the electrostatic force between two charges?

Back

Increasing the distance between two charges decreases the electrostatic force, while decreasing the distance increases the force.

Front

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

Back

If the distance is halved, the electrostatic force increases by a factor of four, according to Coulomb's Law.

Front

What is the relationship between charge and electrostatic force?

Back

The electrostatic force is directly proportional to the product of the magnitudes of the charges; greater charges result in a stronger force.

Front

What occurs when two like charges are brought close together?

Back

Two like charges repel each other when brought close together.

Front

What occurs when two opposite charges are brought close together?

Back

Two opposite charges attract each other when brought close together.

Front

If two charges exert a force of 40 N at a distance of 2 meters, what is the force at 1 meter?

Back

The force at 1 meter would be 160 N, as the force increases with the square of the distance decrease.

Front

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

Back

The formula is 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 them.

Front

What is the value of Coulomb's constant (k)?

Back

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

Front

What is the effect of increasing one of the charges on the electrostatic force?

Back

Increasing one of the charges will increase the electrostatic force between the two charges.
