Electrostatics

Front

What happens to electrostatic force when distance increases?

Back

The electrostatic force decreases; this relationship is inversely proportional.

Front

What occurs when a balloon is rubbed on a student's head?

Back

Negatively charged particles move from the head to the balloon.

Front

How do insulators differ from conductors?

Back

Insulators do not allow charge to freely move.

Front

Which diagram correctly shows the electric field around a negative charge?

Back

Diagram B.

Front

At which point is the electric field the weakest?

Back

Point C because the field lines are further apart.

Front

Define electrostatic force.

Back

The force between charged objects, which can be attractive or repulsive.

Front

What is the principle of conservation of charge?

Back

Charge can neither be created nor destroyed; it can only be transferred.

Front

What is an electric field?

Back

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 positive and negative charges?

Back

Positive charges attract negative charges and repel other positive charges; negative charges do the opposite.
