4. Instead of buying a capacitor, you decide to make one. Your capacitor consists of two circular metal plates, each with a radius of 10 cm. The plates are parallel to each other and separated by a distance of 2 mm. You connect a 12 volt battery across the plates. Find: the capacitance of the capacitor, the charge on each plate and the excess number of electrons on the negative plate. (To get the excess number of electrons, divide the charge on the plate to the basic unit of electric charge)
