Five capacitors are connected purely in series to a 17 volt battery. Three of them have same amount of voltage across them of 2 Volts, the fourth capacitor is 3.0 times the capcitance any of the first three. If the equivalent capacitance of all five capacitors is 2.7 micro-farads, what is the stored energy in the fifth capacitor in micro-joules?
CORRECT answer is 237.15 but I am unable to figure out the work for it
