Electric charges/fields

Front

What is the definition of an electric field?

Back

An electric field is a region around a charged object where other charged objects experience a force.

Front

What is the relationship between the distance of charges and the strength of the electrical force between them?

Back

The electrical force between charges is inversely proportional to the square of the distance between them; as they get closer, the force increases.

Front

What happens to electric charges that are alike?

Back

Electric charges that are alike repel each other.

Front

What happens to electric charges that are opposite?

Back

Electric charges that are opposite attract each other.

Front

What is the formula for calculating the electrostatic force between two point charges?

Back

The electrostatic force (F) can be calculated using Coulomb's Law: F = k * (|q1 * q2| / r^2), where k is Coulomb's constant.

Front

What is Coulomb's constant and its approximate value?

Back

Coulomb's constant (k) is approximately 8.99 x 10^9 N m²/C².

Front

What is the significance of a uniform electric field?

Back

A uniform electric field has the same strength and direction at all points, typically found between two parallel plates.

Front

How does the electric field direction relate to the charges creating it?

Back

The electric field direction is away from positive charges and towards negative charges.

Front

What are the two types of subatomic particles found in the nucleus of an atom?

Back

Protons and neutrons.

Front

What is the charge of a proton and a neutron?

Back

A proton has a positive charge (+1), while a neutron has no charge (0).
