Coulomb's Law Flashcard

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

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 the unit for electrostatic charge?

Back

Coulombs (C) are the standard unit for measuring electric charge.

Front

What happens to the electrostatic force when the distance between two charges increases?

Back

The electrostatic force decreases as the distance between the charges increases.

Front

What happens to the electrostatic force when the magnitude of the charges increases?

Back

The electrostatic force increases when the magnitude of the charges increases.

Front

What type of force exists between two electrons?

Back

A repulsive force exists between two electrons due to their like charges.

Front

What type of force exists between an electron and a proton?

Back

An attractive force exists between an electron and a proton due to their opposite charges.

Front

What is Coulomb's constant (k)?

Back

Coulomb's constant (k) is approximately 8.99 x 10^9 N m²/C² and is used in the calculation of electrostatic force.

Front

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

Back

The force is directly proportional to the product of the charges; if either charge increases, the force increases.

Front

What is the relationship between distance and force according to Coulomb's Law?

Back

The force is inversely proportional to the square of the distance; as distance increases, the force decreases.
