Question

1. what is an example of an object being charged by conduction?

rubbing a glass rod with a silk cloth
clothes tumbling together in a dryer
an aluminum plate touching a metal dome
a comb picking up paper without touching it

Explanation:

• Charging by conduction requires direct contact between objects.
• When an aluminum plate touches a metal dome, charge is transferred through direct contact (conduction).
• Rubbing a glass rod with silk (first option) is charging by friction.
• Clothes tumbling in a dryer (second option) is also due to friction.
• A comb picking up paper without touching (fourth option) is charging by induction (no direct contact).

Answer:

an aluminum plate touching a metal dome
