Front

What is charging a neutral object by rubbing it called?

Back

Charge by friction.

Front

What is the magnitude of the electrostatic force on B due to A if the force on A due to B is 4.0N?

Back

4.0N.

Front

Why does lightning sometimes strike buildings during a storm?

Back

The clouds are polarized with the tops being positive and the bottoms being negative.

Front

What happens to the leaves of a neutral electroscope when a positively charged rod is brought near?

Back

The leaves will spread apart and be positive.

Front

Which statement about electrostatic force is false?

Back

The values of the two charges is always the same.

Front

What is electrostatics?

Back

The study of electric charges at rest.

Front

What is Coulomb's Law?

Back

It describes the electrostatic force between two charged objects, stating that the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Front

What is the unit of electric charge?

Back

Coulomb (C).

Front

What is an electroscope?

Back

A device used to detect electric charge.

Front

What is the principle of conservation of charge?

Back

Charge can neither be created nor destroyed; it can only be transferred from one object to another.
