If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

the silk has become negatively charged.

friction destroyed electrons in the rod.

What happens when you touch a metal doorknob after rubbing your shoes on the carpet?

Millions of electrons go from your finger into the doorknob

The doorknob sends a burst of electric current into your body

The doorknob sends millions of electrons into your finger

Your finger becomes negatively charged

The negatively charged balloon is brought near, not touching, the two cans. What happens?

The negative charges in Can A move away from the balloon

The negative charges in Can B move towards the balloon

The positive charges in Can B move towards the balloon

The positive charges in Can A move away from the balloon

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?

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

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

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

A neutral metal sphere is touched by a positively charged metal rod. During the process, protons are transferred from the positively charged rod to the sphere and the sphere now has a _________________.

nonsense! this is not what happens!

has no charge; it remains neutral

Consider the conduction charging shown.

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

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

Protons move from the bar into the sphere.

Protons move from the sphere into the negatively charged bar.

Two electrically neutral metal spheres, A and B, on insulating stands are placed in contact with each other. A negatively charged rod is brought near, but does not touch the spheres, as shown in the diagram below. How are the spheres now charged?

A is positive and B is negative.

A is positive and B is positive.

A is negative and B is positive.

A is negative and B is negative.
