Capacity of capacitor between 2 and 3 =

ε0d

2d

Potential difference between 2 and 3 is V.
∴ Charge on capacitor formed by plates 2 and 3 is Q = CV =

ε0A

2d

V
Capacity of capacitor between 4 and 5 is C =

ε0A

d

∴ change on plate 5 is Q =

ε0A

d

V
Between 2 and 3 battery of V volts is connected.
∴ Potential difference between 2 and 3 is V.
Plates 2 and 5 are connected to same terminal of battery, so potential differencebetween them is zero
