What happens when you touch a metal doorknob after rubbing your shoes on the carpet?
The doorknob sends a burst of electric current into your body
Millions of electrons go from your finger into the doorknob
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 B move towards the balloon
The negative charges in Can A move away from 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?
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.
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 _________________.
positive charge
negative charge
has no charge; it remains neutral
nonsense! this is not what happens!
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.
