Physics

Three capacitors, all initially without any dielectricsinserted, of C1 = 4 micro-farads, C2 = 10 micro-farads, and C3 = 10micro-farads, are connected purely in series to a battery and thetotal stored energy of all three capacitors is 248 micro-joules.Then, the plates of C1 are brought closer by a factor of 3 and adielectric with a dielectric constant of 1.9 is inserted into C2while still connected in series to the same battery. (C3 does notchange at all.) How much does the total stored energy of all threecapacitors increase in micro-joules after the capacitors arechanged? Not the factor change... how much does the stored energygo up in value. step by step please and thank you!
