Capacitance of a parallel plate capacitor with a metal plate kept inside

[QUOTE="kuruman, post: 6852464, member: 192687"] A capacitor is defined as two separate conductors separated in space such that if one transfers charge ##Q## from one conductor to the other, a potential difference ##V## will exist between the two. The capacitance is defined by the equation you quoted and is a geometrical property. It depends on the shape and configuration of the two conductors, not on whether there is charge ##+Q## on one and ##-Q## on the other. An uncharged capacitor still has capacitance. So your justification that capacitance goes to zero because the modified parallel plate capacitor does not store charge is incorrect. You can always put charge on a conductor in which case there will be a capacitance with the "other conductor" being at infinity. Then the charge you put on this conductor divided by the potential difference between it and infinity is the capacitance. In view of all this, it appears that neither of the given choices is correct. This does not look like a well crafted problem to me. Is this in a textbook? [/QUOTE]
