You rub your feet on the carpet in your warm living room on a cold winter day. You know you have gained static electrical charge on your body. You decide to touch your sister to shock her. Your sister knows that in order to reduce the electrical shock she will feel when you touch her, she (A)must stand very still (B) hold on to a doorknob (C)jump up and down at exactly 60 Hertz (D)rub her feet on the carpet I have narrowed this down to answers B and D. I am leaning toward answer B, because if the sister rubs her feet on the carpet, as in answer D, there still might be a charge differential between the two people and therefore there would still be a shock. I think, but am not sure, that B would "ground" the charge. Please help!
