What happens to the electric force between two charged objects if the charge on each is doubled while the distance remains the same?

Back

The electric force becomes four times as great.

Front

Which fundamental force causes like-charged particles to repel each other?

Back

Electromagnetic force.

Front

What occurs when two negatively charged balloons are brought closer together?

Back

The magnitude of the electrostatic force between the balloons increases, and they repel each other.

Front

What is the term for the contact of a charged object with a neutral object?

Back

Conduction.

Front

What is true about the gravitational force between two objects?

Back

It is directly proportional to the product of their masses.

Front

What is the formula for calculating the electric force between two charges?

Back

F = k * (|q1 * q2| / r^2), where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.

Front

What is the difference between conduction and induction in terms of charging objects?

Back

Conduction involves direct contact, while induction involves the influence of a charged object without direct contact.

Front

What is the role of the strong nuclear force?

Back

It holds protons and neutrons together in the nucleus of an atom.

Front

What is the weak nuclear force responsible for?

Back

It is responsible for the process of beta decay in radioactive materials.

Front

How does distance affect the gravitational force between two objects?

Back

The gravitational force is inversely proportional to the square of the distance between the objects.
