9. If you were wearing the sweater shown and rubbed your hand on it, you too would gain some negative charge on your hand. Then when you directly touch a metal conductor, like a door knob, you will feel a shock. This is called Conduction. From this scenario, where does the negative charge go when you touch a door knob?

When you touch a door knob, the negative charge gained from rubbing the sweater is transferred through conduction to the metal conductor, which in this case is the door knob. The negative charge flows from your hand to the door knob, thereby equalizing the charge imbalance and resulting in a shock sensation.
