The capacitance of a parallel-plate capacitor is 8.4 picofarad. It consists of two parallel plates separated by a distance of 2 mm. Calculate the area of each plate. After charging the capacitor using a 6 V battery, it is disconnected from the charging voltage and the separation between the plates is reduced to 0.55mm. What is the new capacitance of the capacitor? Calculate the new potential difference between the plates.
