An air-filled (empty) parallel-plate capacitor is made from two square
plates that are 27 cm on each side and 1.00 mm apart. The capacitor is connected to a 45 V battery and fully charged. It is then disconnected from the battery and its plates are pulled apart to a separation of 2.30 mm.
(a)What is the capacitance of this new capacitor (in nF)?
_____________nF
(b)What is the charge on each plate (in nC)?
____________ nC
(c) What is the electrical field between the plates (in kV/m)? (Enter the magnitude.)
______________kV/m
