10 identical capacitors each of capacitance C are connected in series with a battery of emf V and fully charged Now the battery is removed and the capacitors are connected in parallel with positive terminals of 8 capacitors and negative terminals of 2 capacitors at a point and negative terminals of 8 capacitors and positive terminals of 2 at other point The common potential R charge on each capacitor is
