Distribution of Charges

A negative balloon moves near a conducting neutral sphere, and a hand touches it. Where will e- flow?

• e- move into the sphere

• e- move into the hand

• e- move towards the hand but stay in the sphere

• e- move towards the sphere but stay in the hand

The negatively charged balloon is brought near the two cans. What happens?

• The negative charges in Can B move towards the balloon through can A

• The negative charges in Can A move away from the balloon through can B

• The positive charges in Can B move away from the balloon

• The positive charges in Can A move toward the balloon

Physics students studied various behaviors and features of charged particles and how they interact with other charged materials. The image below shows the results of sending a charged particle through two oppositely charged electric plates. What is the charge on the particle moving between the two electrically charged plates shown based on its movement?

• positive

• negative

• neutral

• cannot be determined

A positively charged balloon is brought near an aluminum can, and a hand touches the can. How will electrons move?

• e- will move from the can into the hand away from the balloon

• e- will move from the hand into the can towards the balloon

• e- will move towards the hand, but stop at the end of the can

• e- will move towards the can, but stop at the end of the hand

Which of these is the best definition of polarization?

• The object gains a positive or negative charge from another object.

• The charges in a neutral object separate due to a nearby charged object.

• Charges on a neutral object jump off onto a charged object due to attraction of opposite charges.

• Two objects attract each other because they are both charged.

If you bring a charged object near an electrically neutral surface without allowing the object to touch the surface, the charges in the surface are rearranged by

• friction.

• convection.

• induction.

• conduction.

A neutral metal pan is brought near a negative charged plate. A hand touches the pan. What is the result?

• electrons move into the hand; the pan is negative

• protons move into the pan; the pan is positive

• electrons move into the pan; the pan is negative

• electrons move into the hand; the pan is positive
