- You have likely experienced "static shock" recently. The magnitude of charge transferred when you walk across a carpet, reach out and touch a doorknob, and unintentionally give yourself that static shock is around 1.88 nC (nC stands for nano-Coulomb). In units of Giga-electrons, about how many electrons are transferred when you experience static shock?how many electrons must be removed from a neutral , isolated conducting sphere to give it a positive charge of 1.0 x 10 ^6 C.There are three objects: A, B, and C. You know that A is positively charged. When object A is brought near object B, they attract. When object B is brought near object C, they also attract. What can you say about the charge of object B?(a) Object B CAN be either neutral or negative. (b) Object B MUST be neutral.(c) Object B CAN be either neutral or positive.(d) Obejct B MUST be positive.(e) Object B MUST be negative.
