Friction Conduction Induction

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

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

A metal block has a net -10 charge. What will happen when a neutral grounding wire touches the block?

• The block will gain protons until it is neutral

• Electrons will flow out of the ground wire and into the block until the block is neutral

• Electrons will flow out of the block, into the ground wire until the block is neutral

• The block will gain electrons and become more negative

To charge this electroscope, first it must be grounded with a conductor. Then a positive charged rod is brought near. What happens next?

• The leaves will gain a charge and stay in place

• The rod must touch the electroscope to transfer charge, and you can observe the leaves move

• The plate must be taken off in order to allow electrons to transfer

• You can't charge something while it is grounded, because ground wire don't let electrons flow
