Physics 101 Mechanics

In yet another photoelectric experiment it is found that a stopping potential of 1.00 V is needed to stop all of the electrons when the incident light of wavelength 260 nm is used, and 2.30 V when the incident light has wavelength 207 nm. From this data determine:
(i) Planck's constant, and
(ii) the work function of the metal.
