Given that a photon of light of wavelength $$10,000\, \mathop {\rm{A}}\limits^ \circ $$ has an energy equal to $$1.23\, eV$$. When the light of wavelength $$5000 \mathop {\rm{A}}\limits^ \circ$$ and intensity $$I_o$$ falls on a photoelectric cell, the saturation current is $$0.40 \times 10^{-6} \,A$$ and the stopping potential is $$1.36\, V$$.
if the intensity of light is made $$4I_0$$, then the stopping potential will become
