Coulombs Law

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 charges and inversely proportional to the square of the distance between them.

Front

What is the unit of electric charge?

Back

Coulombs (C) are the units used to measure electric charge.

Front

What is the unit of force in the International System of Units (SI)?

Back

Newtons (N) are the units used to measure force.

Front

What does the term 'electrostatic force' refer to?

Back

Electrostatic force refers to the force of attraction or repulsion between charged objects.

Front

How does distance affect the electrostatic force between two charges?

Back

The electrostatic force decreases as the distance between the charges increases, following an inverse square relationship.

Front

If the charge of an object doubles, what happens to the electrostatic force?

Back

If the charge of an object doubles, the electrostatic force also doubles, assuming the distance remains constant.

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, and it is used in Coulomb's Law.

Front

What happens to the electrostatic force if the distance is halved?

Back

If the distance is halved, the electrostatic force increases by a factor of four, since force is inversely proportional to the square of the distance.

Front

What is the significance of the sign of the charges in Coulomb's Law?

Back

The sign of the charges determines the nature of the force: like charges repel each other, while opposite charges attract.
