Coulombs Law

Front

What happens when a balloon is rubbed on a student's head?

Back

Negatively charged particles move from head to balloon.

Front

Which two particles are attracted to each other?

Back

A proton and an electron.

Front

What is the value of the constant in Coulomb's equation?

Back

k = 9 ·10^9.

Front

What happens to the electrical force between two oppositely charged particles as they approach each other?

Back

The attractive force increases.

Front

What type of force exists between two protons?

Back

A repulsive force.

Front

Define 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 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 the constant 'k' represent in Coulomb's Law?

Back

Coulomb's constant, which quantifies the amount of force between two charges.

Front

What is the effect of distance on the electric force between two charges?

Back

As the distance increases, the electric force decreases.

Front

What type of charge do electrons have?

Back

Electrons have a negative charge.
