Understanding Coulomb's Law

Front

What does Coulomb's Law describe?

Back

The electrostatic force between two charged objects.

Front

Formula for Coulomb's Law

Back

F = k * |q1 * q2| / r^2

Front

What is the unit of charge in the SI system?

Back

coulomb

Front

How does the distance between two charges affect the force between them according to Coulomb's Law?

Back

The force decreases as the distance between the charges increases.

Front

If the charge of one object is doubled, how does the force change?

Back

The force doubles.

Front

What is the significance of the constant k in Coulomb's Law?

Back

Coulomb's constant k signifies the strength of the electrostatic force between charges.

Front

Explain how Coulomb's Law applies to point charges.

Back

Coulomb's Law describes the electrostatic force between two point charges, proportional to the product of their charges and inversely proportional to the square of the distance between them.

Front

What happens to the electrostatic force if both charges are negative?

Back

The electrostatic force is repulsive.

Front

Can Coulomb's Law be applied in a medium other than vacuum?

Back

Yes, Coulomb's Law can be applied in a medium other than vacuum.
