Five identical plates each of area A are joined as shown in the figure. The distance between the plates is d. The plates are connected to a potential difference of V volts . The charge on plates 1 and 4 will be

The given circuit can be redrawn as follows. All capacitors are identical and each having capacitance|Charge on each capacitor| = |Charge on each plate|Plate 1 is connected with positive terminal of battery so charge on it will be Plate 4 comes twice and it is connected with negative terminal of battery, so charge on plate 4 will be
