Activity 2.2 PS9

As the distance between two charged objects increases, the strength of the electrical force between the objects __________.

• varies

• remains the same

• increases

• decreases

As the amount of charge on two objects increases, the strength of the electrical force between the objects __________.

• increases

• decreases

• varies

• remains the same

Which change will decrease the electric force between two positively charged objects?

• moving them closer together

• moving them farther apart

• adding neutrons

• removing electrons

Which factors affect the strength of the electric force between two objects?

• the mass of the objects and the distance between the objects

• the amount of charge on the objects and the type of charge on the objects

• the distance between the objects and the amount of charge on the objects

• the mass of the objects and the amount of charge on the objects

A region around charged objects where the object´s electric force is exerted on other charged objects is an electric: 

• Field
• Outlet
• Socket
• Power plant 

Two like charges:

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

Which type of charges do these balloons have?

• like charges
• opposite charges

The closer the charges, the ___________ the force between them

• closer
• further
• stronger
• weaker

Which statement best describes the electric fields in the image?

• The charges are neutral.

• Both charges are negative, so the field lines are alike.

• The field lines move toward a positive charge and away from a negative charge.

• The field lines move away from a positive charge and toward a negative charge.

Which diagram correctly shows the electric field around a negative charge?

• A

• B

• they are both positive
