# Mini-Quiz: Static Electricity Forces

by Ron Kurtus (15 February 2009)

Take this Mini-Quiz to check your understanding of the lesson material.

1. Why is there a force of attraction between opposite electrical charges?

Opposites repel

They are both magnetic

It is a property of electrical charges

2. Would two tennis balls on strings and with like charges repel each other?

No, because tennis balls only attract each other

Yes, but you would barely notice it because the balls are so heavy

Only if hit with a tennis racquet

3. What is another example of a charged object attracting neutral objects?

It only works with balloons

The movement of a compass with a magnet

Bits of paper can be attracted to a charged comb

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

Science is amazing
