PS2.B Flashcard

Front

What is the electromagnetic interaction responsible for?

Back

The electromagnetic interaction is responsible for the repulsion between two like charges.

Front

How does increasing the mass of one object affect the gravitational force between two objects?

Back

Increasing the mass of one object doubles the gravitational force between them.

Front

What happens to the gravitational force if the distance between two objects is tripled?

Back

The gravitational force becomes 1/9 as much.

Front

Which interaction is crucial for the stability of atomic nuclei?

Back

The strong nuclear interaction is crucial for the stability of atomic nuclei.

Front

What type of interaction occurs when a charged particle is influenced by an external magnetic field?

Back

The electromagnetic interaction occurs when a charged particle is influenced by an external magnetic field.

Front

Define gravitational force.

Back

Gravitational force is the attractive force between two masses.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the role of the strong nuclear force?

Back

The strong nuclear force holds protons and neutrons together in the nucleus of an atom.

Front

What is the difference between electromagnetic and gravitational forces?

Back

Electromagnetic forces can be both attractive and repulsive, while gravitational forces are always attractive.

Front

What is the weak nuclear force responsible for?

Back

The weak nuclear force is responsible for processes like beta decay in radioactive materials.
