Two neutral conducting pop cans are touching each other. A negatively charged balloon is brought near Can X as shown below. Which of the following occur as the balloon approaches Can X?

• The electrons are transferred or move from the balloon to can X to make it negatively charged

• Can X becomes positively charged because it loses electrons

• Can X becomes positively charged because the electrons are repelled and move to Can Y.

• The protons from the balloon move to Can X to make it positively charged.

Consider the conduction charging shown.

• Electrons move from the charge metal bar and into the sphere staying clumped together

• Protons move from the bar into the sphere.

• Electrons move from the charged metal bar into the sphere and evenly distribute themselves.

• Protons move from the sphere into the negatively charged bar.
