Sara walks across a rug on the floor when the doorbell rings. She opens a door and gets a shock. What type of charge will Sara have after the shock? Explain how you know in 1-2 sentences.(2 points)
Well, after getting a shock, Sara might have a bit of a "charged" personality! But in terms of actual electric charge, she would have an excess of electrons since she experienced a static shock.
To determine the type of charge Sara will have after getting a shock, we need to understand that rubbing generates static electricity. If Sara gets a shock by touching a metal door, it means she accumulated excess negative charges through the friction, giving her a negative charge. If she got shocked by touching a positive charge, it means she accumulated positive charges during the rubbing.
Sara will have a negative charge after the shock. This is because when she walked across the rug, friction caused the transfer of electrons from her body, leaving her with an excess of positive charges.
