Hi there!
Recall the equation for spring potential energy:

k = Spring constant (N/m)
x = extension of spring from equilibrium (m)
PE = Potential Energy (J)
Plug in the given values:

Answer:
Explanation:
Energy of radiation in eV = 1237.5/280 = 4.42 eV.
Work function = 2.65 eV.
Maximum kinetic energy = 4.42 - 2.65 = 1.77 eV.
