Electric Charge & Coulomb's Law

Front

What happens to the electrostatic force if each of the charges doubles?

Back

The force quadruples.

Front

How do electrons differ from protons?

Back

Electrons hold a negative charge and protons hold a positive charge.

Front

According to Coulomb's Law, when the distance increases, the electrostatic force ____________; we call this relationship ____________ proportional.

Back

decreases; inversely.

Front

What happens when two like charges interact?

Back

They repel each other.

Front

If the force of interaction between two charged particles is 2.4 N, what would the force be when the distance doubles?

Back

0.6 N.

Front

Define electric charge.

Back

Electric charge is a property of subatomic particles that causes them to experience a force when placed in an electromagnetic field.

Front

What is Coulomb's Law?

Back

Coulomb's Law states that the electrostatic 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 unit of electric charge?

Back

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

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.

Front

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

Back

The force increases by a factor of four.
