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 increases?

Back

The electrostatic force decreases.

Front

What is the relationship between distance and electrostatic force?

Back

The relationship is inversely proportional.

Front

What is the principle of induction in electrostatics?

Back

Induction is the process of transferring charge to an object without direct contact.

Front

What do insulators do in terms of electron flow?

Back

Insulators inhibit the flow of electrons.

Front

What is the unit of charge?

Back

The unit of charge is the Coulomb (C).

Front

What is the significance of the electrostatic force in everyday life?

Back

The electrostatic force is responsible for various phenomena, including static electricity, the behavior of charged objects, and the functioning of electronic devices.

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.

What is Coulomb's constant and its value?

Back

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

Front

What is the difference between conductors and insulators?

Back

Conductors allow the flow of electric charge, while insulators do not.
