Electric Charge

Objects with like charges repel and unlike charges attract. The girl's hair and the comb have-

• unlike charges
• like charges
• neutral charges
• no charges

Some clothes are pulled out of a dryer and they are all sticking together! What is causing this? 

• Induced charge from friction
• Induced charge from contact
• Static charge from friction
• Static charge from contact

What type of charge do these balloons have?

• like charges
• opposite charges

Which type of charges do these balloons have?

• like charges
• opposite charges

Two balls are placed near one another and hang down, as shown below.

Which conclusion is supported by this evidence?

• Neither ball has a charge.

• The balls are both positively charged.

• One ball is positively charged, and the other is negatively charged.

• Each ball has a charge, but the type of charge is unknown.

If the two charges represented in the figure were brought near each other, they would

• attract each other.
• repel each other.
• cause static discharge.
• have no affect on each other

Two like charges:

•  neutralize each other.
• repel each other. 
• must be neutrons. 
• attract each other.

Charging by Friction results in two objects with the same charge.

• True
• False

A balloon becomes negatively charged when rubbed against a head of hair because

• the balloon loses electrons to the hair

• the balloon loses protons to the hair

• the hair loses protons to the balloon

• the hair loses electrons to the balloon
