Electric Charges and Fields

At which point is the electric field the weakest?

• because it is the furthest away

• because the field lines are further apart

• because the field lines are further apart

•  because it is the furthest away

• A

• B

• C

• D

The electrical force between charges is strongest when the charges are

• close together

• far apart

•  the electric force is constant everywhere.

• there is no pattern

The electric field lines for a positive charge is always directed away from the charge. True or False?

• True

• False

The space around an electric CHARGE that causes them to attract and repel is called a(n)...

• Gravity

• Electric Field

• Magnetism

• None of the above

Match the following.

• allows charge flow

• conductor

• region of influence

• neutral charges

• attract

• opposite charges

Like charges:

• attract

• repel

• create an electrical current

• create a magnetic field

NGSS.MS-PS2-3

The buildup of charges on an object is called

• Electric Current

• Static Electricity

• Magnetism

• Electrical Discharge

When two objects have the same charge, they are (such as + and +)

• Attracted to each other

• Repelled by each other

• Have no effect on each other
