Question

27. Light described at a place by equation
E = 200
ex 10155-')t + sin(10 x 1016 s=")]
falls on metal surface having work function 2 eV, the
maximum kinetic energy of photoelectrons?
(1) 8 eV
(2) 10 eV
(3) 4.59 eV
(4) 3.27 eV​

Answer 1

Answer:

4.56

Explanation:

work done = max k.E to process required electron gain by metal surfaces
