Coulomb's Law Flashcard

Front

What is the unit for electrostatic charge?

Back

Coulombs

Front

According to Coulomb's Law, when the distance increases, the electrostatic force ____________.

Back

decreases

Front

Coulomb’s law states that the force between two charged objects will __________ when the magnitude (value) of the object’s charge increases.

Back

increase

Front

An attractive force exists between which two particles?

Back

An electron and a proton.

Front

What does Coulomb's Law describe?

Back

The relationship between the electrostatic force, the charges involved, and 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 Coulomb's constant (k)?

Back

Approximately 8.99 x 10^9 N m²/C².

Front

What happens to the electrostatic force if the distance between two charges is halved?

Back

The electrostatic force increases by a factor of four.

Front

What type of force is described by Coulomb's Law?

Back

Electrostatic force, which can be attractive or repulsive.

Front

What is the effect of like charges on each other according to Coulomb's Law?

Back

Like charges repel each other.
