Coulomb's Law

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

Back

The force increases by a factor of 4, as it is inversely proportional to the square of the distance.

Front

What is the unit of electric charge?

Back

The unit of electric charge is the Coulomb (C).

Front

What type of charges repel each other?

Back

Like charges repel each other (e.g., two positive charges or two negative charges).

Front

What type of charges attract each other?

Back

Opposite charges attract each other (e.g., a positive charge and a negative charge).

Front

If the charge of one particle is increased by 6 times, how does it affect the electrostatic force?

Back

The electrostatic force increases by 6 times.

Front

What is the relationship between electric force and distance?

Back

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

Front

What happens to the electric force if both charges are doubled?

Back

The electric force increases by a factor of 4, as it is directly proportional to the product of the charges.

Front

What is an example of a negatively charged object?

Back

An example of a negatively charged object is a rubber rod that has been rubbed with fur, gaining extra electrons.

Front

What is the effect of distance on the strength of the electric force?

Back

The strength of the electric force decreases as the distance between the charges increases.
