1.	A metal foll of negative thickness is intorduced between two plates of a capacitor at the center. What will be the new capacitance of the capacitance ?
Answer» On intorducing a thin metal foil d is hallved, Arrangment is equivalent to two conderers each of capacity 2C in series. `:. (1)/(C_(s)) = (1)/(2C) + (1)/(2C) = (1)/(C ) :. C_(s) = C` Capacity is uncharged.
