Electric Charges

Front

What are the two types of electric charges?

Back

Positive charge and negative charge.

Front

How do opposite charges interact?

Back

They attract each other.

Front

How do like charges interact?

Back

They repel each other.

Front

What is the net charge if there are +5 units of positive charge and -4 units of negative charge?

Back

Net charge = +1.

Front

Can an object have a neutral charge?

Back

Yes, an object can be neutral if it has equal amounts of positive and negative charges.

Front

What is the principle of conservation of charge?

Back

The total electric charge in an isolated system remains constant.

Front

What happens to the force between two charges if the distance between them is doubled?

Back

The force decreases to one-fourth of its original value (inverse square law).

Front

What is 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 unit of electric charge?

Back

Coulomb (C).

Front

What is the difference between conductors and insulators?

Back

Conductors allow electric charges to flow freely, while insulators do not.
