A monochromatic light of frequency f is ...

A monochromatic light of frequency f is incident on two identical metal spheres of threshold frequency `f/2` and `f/3` respectively. After some time, emission of photoelectron will stop on both spheres . Now both metal spheres are connected through wire. (radius of spherhes is R )
(a)What will be potential of spheres now ?
(b)how many electron will flow through wire ?
