electric field

The girl's hair and the comb are attracting one another. The hair and the comb have

• opposite charges

• like charges

• no charges

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

the object that lose electrons will have a charge that is...

• negative

• positive

• neutral

Static electricity can be built by friction, conduction or induction. In the case of the finger it got charged by:

• Friction

• Conduction

• Induction

Materials that easily lose or accept electrons are considered

• Good conductors

• Good insulators

• Good anti-static agents

• Good for storing charge

• A
• B
• C
• D

which is the field for opposite charges

• 
• 
• 
• 

Which diagram correctly shows the field lines between two like charges?

• A

• B

• Both

• Neither

When an object gains electrons it becomes __________

• Neutral

• Positively charged

• Negatively charged

The flow of electric charges is 

• voltage
