electrostatic quiz - charging and sticky tape lab

What does polarization of charge mean?

• charges move from one object to another

• charges repel one another

• charges attract one another

• charges separate due to the presence of a nearby charged object

What is the charge on a balloon rubbed on a wool sweater before and after?

• neutral first, then positive

• neutral first, then negative

• positive first, then negative

• negative first, then positive

What process allows a neutral object to be attracted to a charged object?

• refraction

• polarization

• diffraction

• photoelectric effect

Two neutral blown up balloons are tied on either end of a piece of string. A physics student holds the middle of the string so they now have 2 balloon pendulums. What is the interaction between the balloons at this point?

• Both are neutral, so they just hang there.

• Both are positive, so they repel

• One is positive and one is negative so they attract.

Two neutral blown up balloons are tied on either end of a piece of string. A physics student holds the middle of the string so they now have 2 balloon pendulums. Another student rubs one balloon with a piece of silk. What is the interaction between the balloons at this point?

• Both are neutral, so they just hang there.

• Both are positive, so they repel

• One is positive and one is negative so they attract.

• One is negative and the other is neutral so they attract

For the sticky tape lab, why was the strip of paper attracted to both the top and bottom pieces of tape once they'd been jerked apart?

• the paper is positive because it has a low electron affinity

• the paper is neutral and the strips are + and -

• the paper is negative and both pieces of tape were positive

For the sticky tape lab, what was the purpose of charging the PVC pipe or graduated cylinder?

• to identify the charge on the tape strips

• to identify the charge on the bag and pipe/cylinder

• to identify the charge on the base tape on the table
