Coulomb's Law Flashcard

Front

What is Coulomb's Law?

Back

Coulomb's Law describes the 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 is the unit of charge in Coulomb's Law?

Back

Coulomb (C) is the unit of electric charge.

Front

In Coulomb's Law, what does 'r' represent?

Back

The distance between the centers of the two charges.

Front

What happens to an object when it gains electrons?

Back

It becomes negatively charged.

Front

What is Coulomb's constant (k)?

Back

Coulomb's constant (k) is approximately 8.99 x 10^9 N m²/C², and it quantifies the strength of the electrostatic force between two charges.

Front

How does the distance between charges affect the force between them?

Back

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

Front

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

Back

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

Front

If the distance between two charges is halved, what happens to the force?

Back

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

Front

What is the effect of like charges on each other?

Back

Like charges repel each other.
