Hiro rubs an inflated balloon on his hair, and his hair sticks to the balloon. As he moves the balloon away from his head, how does the electric force change?

A
The electric force increases because the balloon loses its charge.
B
The electric force increases because the distance increases.
C
The electric force decreases because the distance increases.
D
The electric force decreases because his hair loses its charge.

How does increasing the amount of charge on an object affect the electric force it exerts on another charged object?

A
The electric force increases because the amount of charge has an indirect relationship to the force.
B
The electric force increases because the amount of charge has a direct relationship to the force.
C
The electric force decreases because the amount of charge has an indirect relationship to the force.
D
The electric force decreases because the amount of charge has a direct relationship to the force.

A negatively charged rod is placed near two neutral metal spheres, as shown below.

Question illustration
A
The spheres are charged through friction.
B
The spheres develop the same charge.
C
Electrons move from the rod to Sphere A.
D
Electrons move from Sphere A to Sphere B.
5

What would make oppositely charged objects attract each other more?

A
increasing the positive charge of the positively charged object and increasing the negative charge of the negatively charged object
B
decreasing the positive charge of the positively charged object and decreasing the negative charge of the negatively charged object
C
increasing the distance between the positively charged object and the negatively charged object
D
maintaining the distance between the positively charged object and the negatively charged object
6

An electroscope is a device that detects charge on objects that touch it or are brought near it. John rubs a piece of cotton fabric on a plastic rod and then touches the rod to the electroscope.

A
John charges the rod through induction, then charges the electroscope through friction.
B
John charges the rod through conduction, then charges the electroscope through induction.
C
John charges the rod through friction, then charges the electroscope through induction.
D
John charges the rod through friction, then charges the electroscope through conduction.

Shareen performs a skit to model a method of charging. In the skit, a painter shakes her hand and gets paint on her.

A
It models induction because the painter represents a neutral object and the paint represents electrons that are transferred through rubbing.
B
It models conduction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
C
It models induction because the painter represents a charged object and the paint represents electrons that are transferred through contact.
D
It models conduction because the painter represents a neutral object and the paint represents electrons that are transferred through rubbing.
8

Which change increases the electric force between objects?

A
Two neutral objects are moved closer together.
B
Electrons are added to two negatively charged objects.
C
Two oppositely charged objects are moved farther apart.
D
The charge on two positively charged objects is reduced.
9

A plastic rod becomes negatively charged when it is rubbed with a piece of wool. How does the rod become charged?

A
Electrons move from the rod to the wool.
B
Protons move from the rod to the wool.
C
Electrons move from the wool to the rod.
D
Protons move from the wool to the rod.
10

What is the name of the area around a charged object where the object can exert a force on other charged objects?

A
electric field
B
electric charge
C
electric induction
D
