An air spaced parallel plate capacitor is connected to a 12 v battery.
(A) If 36 uC of charge flows onto the plates, find its capacitance.
(B) If a slab of pyrex glass is inserted between the plates filling the gap, find the new capacitance of the capacitor.
(C) If the capacitor remained attached to the battery when the glass was inserted, what charge is now on the plates?
