Identical capacitor A and B, each plate area $S$ and separation between the plates d are connected in parallel. Charge $Q$ is given to each capacitor. Whole arrangement is shown in figure
 

Now keeping one plate (1) of capacitor $C_2$ fixed, another plate (2) is moved towards the first with very small constant velocity ‘$v$’ from t=0 and keeping one plate (2) of  $C_1$ fixed another plate(1) is moved away from the first plate with same small constant velocity ‘$v$’ from t=0.
