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.
6

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.
7

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.

B
X: negativeY: neutral
C
X: negativeY: neutral
D
X: positiveY: positive
9

A small, positively charged ball is moved close to a large, positively charged ball. Which describes how the small ball likely responds when it is released?

A
It will move toward the large ball because like charges repel.
B
It will move toward the large ball because like charges attract.
C
It will move away from the large ball because like charges repel.
D
It will move away from the large ball because like charges attract.
