A capacitor C stores charge Q when there is a potential differenceV. When a potential difference of
(a)V + 12.5 Volts is used, an extra 45.5 .C of charge is stored.What is the capacitance C?
(b)A second capacitor C has a plate separation of 4.5 mm. When theplates are separated an extra 2.0 mm
the capacitance decreases by 7.5 .F. What is the capacitance?
