A woman rubs her feet on the carpet and gives a shock to her identical twin. If the twin also rubs her feet on the carpet before being touched, the shock will be
1. larger.
2. smaller.
3. the same size.
1. larger.
2. smaller.
3. the same size.
是smaller吧，因为同样的电性（同为正或者同为负），它们之间不存在电势差，所以电子不会轻易移动，电流也很小，所以被电到的感觉应该变小
I think the answer should be (2). Based on the introduction about this problem, if their feet rub on the same material, they will the same kind of eletrons, both positive or alternatively. The do not have the voltage difference, so the electrons will not move between. There's much less current generated, so they will feel smaller shock!
现在物力题怎么这样啊？
