For the given solution :

 At cathode :-    Reaction with greater E0 will take place.

                                     Ag^+\ +\ e^-\ =\ Ag_{(s)}

At anode :-     Self ionisation will take place due to presence of water.

                               H_2O\ \rightarrow\ 2H^+\ + \frac{1}{2}O_2\ +\ 2e^-

Hence, silver will get deposited at the cathode and O2 will be produced from anode.
