1. Two students are trying to decide whether or not Object A is charged and what type of charge it has. They bring Object A near a positively charged strip of tape and observe attraction. Which one of the following additional test O Object A is brought near neutral paper bits and attraction is observed. O Object A is brought near an object of unknown charge type and repulsion is observed. O Nonsense! Knowing that Object A attracts the positively charged strip of tape is conclusive evidence that Object A is charged negatively. 2. When an insulator becomes charged, the charge evenly distributes itself across the entire surface. O True O False 3. A positively charged balloon is brought near to a metal pop can as shown in the diagram at the right. Which statement describes what happens as the balloon approaches the can? O Electrons move from the balloon to the can. O Electrons move from the can to the balloon.. O Electrons within the can move away from the balloon's side. O Electrons within the can move towards from the balloon's side.

Short Answer
1. Two students are trying to decide whether or not Object A is charged and what type of
charge it has. They bring Object A near a positively charged strip of tape and observe
attraction. Which one of the following additional test
O Object A is brought near neutral paper bits and attraction is observed.
O Object A is brought near an object of unknown charge type and repulsion is observed.
O Nonsense! Knowing that Object A attracts the positively charged strip of tape is
conclusive evidence that Object A is charged negatively.
2. When an insulator becomes charged, the charge evenly distributes itself across the entire
surface.
O True
O False
3. A positively charged balloon is brought near to a metal pop can as shown in the diagram at
the right. Which statement describes what happens as the balloon approaches the can?
O Electrons move from the balloon to the can.
O Electrons move from the can to the balloon.
O Electrons within the can move away from the balloon's side.
o Electrons within the can move towards from the balloon's side.
4. Two identical small charged spheres are a certain distance apart, and each one initially
experiences an electrostatic force of magnitude F due to the other. With time, charge
gradually leaks off of both spheres. When each of the spheres has lost half its initial charge,
the magnitude of the electrostatic force will be
01/16 F.
O 1/8 F.
O 1/4 F
0 1/2 F.
5. When two point charges are a distance d part, the electric force that each one feels from the
other has magnitude F. In order to make this force twice as strong, the distance would have
to be changed to
O 2d
o √24
Od/√2
Od/2
Od/4
