Coulombs Law

Front

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

Back

Coulomb (C)

Front

Which two particles are attracted to each other?

Back

A proton and an electron.

Front

What happens to the electric force as the distance between two charges decreases?

Back

The electric force increases.

Front

In a good insulator, how are electrons typically arranged?

Back

Electrons are tightly bound in place.

Front

What type of force exists between two protons?

Back

A repulsive force.

Front

What is Coulomb's Law?

Back

Coulomb's Law states that the electric force between two charged objects is directly proportional to the product of the magnitudes of their charges and inversely proportional to the square of the distance between them.

Front

What is the formula for calculating the electric force using 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 does Coulomb's constant (k) represent?

Back

Coulomb's constant (k) is a proportionality factor in Coulomb's Law, approximately equal to 8.99 x 10^9 N m²/C².

Front

What is the effect of charge magnitude on the electric force?

Back

The greater the magnitude of the charges, the stronger the electric force between them.

Front

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

Back

The electric force is inversely proportional to the square of the distance between the charges.
