Redox Reactions and Electrochemistry: JEE Main 2020 Chemistry question

The photoelectric current from Na (Work function, w₀ = 2.3 eV) is stopped by the output voltage of the cell Pt(s) | H₂ (g, 1 Bar) | HCl (aq., pH =1) | AgCl(s) | Ag(s). The pH of aq. HCl required to stop the photoelectric current form K(w₀ = 2.25 eV), all other conditions remaining the same, is _______ $\times$ 10⁻² (to the nearest integer). Given, 2.303${{RT} \over F}$ = 0.06 V; $E_{AgCl|Ag|C{l^ - }}^0$ = 0.22 V
