Choose the incorrect one?

• A. A parallel plate capacitor is charged and then disconnected from battery. The plates of the capacitor are pulled apart so as to make the distance double between the plates.The energy stored in Capacci
• B. A airfilled capacitor is charged and then disconnected from battey.If now a dielectric is inserted between the plates,then Potential difference will decrease between the plates
• C. Capacitance does not depend on Q and V,it depends on the shape,size ,relative poistion of plates and also on the material which seperates them
• D. None of the above
