An air-filled (empty) parallel-plate capacitor is made from two square plates that are 28 cm on each side and 1.00 mm apart. The capacitor is connected to a 49 V battery and fully charged. It is then disconnected from the battery and its plates are pulled apart to a separation of 2.50 mm. (a) What is the capacitance of this new capacitor (in nF)? (b) What is the charge on each plate (in nC)? (c) What is the electrical field between the plates (in kV/m)? (Enter the magnitude.)
