when a capacitor is connected to a battery terminals, some charge q ( +q on one surface and -q on the other surface) is obtained.but what about the outer surfaces of the capapcitor does it contain charge ? for instance, consider a plate which is given a charge q.q/2 gets distributed on both d surfaces.when another uncharged plate is brought near this a charge -q/2 ia induced on the inner surface and +q/2 on the outer surface. is this what happens when a capacitor is connected to a battery?i mean, is there some charge on the outer surfaces ?

Definitely charge will be on both surface as it is a conductor, but there won’t be any change in the electric field inside the capacitor if you assume the charge Q to be distributed on one surface or q/2 on both, as evident from Gauss’ law.
