Solve the given problem:

Problem: Radiation of a certain wavelength causes electrons with a maximum kinetic energy of 0.68 eV to be ejected from a metal whose work function is 2.55 eV.

A- What will be the maximum kinetic energy (in eV) with which this same radiation ejects electrons from another metal whose work function is 2.07 eV?

I have been stuck on this problem for a long time, please help. Show steps. THANKS!
