A metal sphere, sphere A, has an excess of 40 electrons and it comes into contact with sphere B, a metal sphere with an excess of 20 electrons. After contact they are separated - how many excess electrons are located on sphere B?

• 60

• 30

• 20

• 0

A metal sphere, sphere A, has -15 units of charge and it comes into contact with sphere B which has +31 units of charge. How many units of charge are on sphere B following contact?

• +31

• +16

• +8

• -15

A balloon is rubbed on a student's head. What occurs because of this?

• Charged particles on the balloon are destroyed

• Positively charged particles move from head to balloon

• Charged particles from the balloon are released into the air

• Negatively charged particles move from head to balloon

Electricity can flow easily through these. 

• conductors
• insulators

Insulators:

• Encourage the flow of protons

• Resist the flow of protons

• Encourage the flow of electrons

• Resist the flow of electrons

When a positively charged rod touches a neutral object

• Electrons flow from the neutral object to the positive object

• Protons flow from the positive object to the neutral object

• Electrons flow from the positive object to the neutral object

• No charges are transferred
