Question 34 NECO • 2024 • PHYSICS • objective

An electron in a hydrogen atom makes a transition from the \(n=5\) level to the \(n=2\) level, emitting a photon. This photon is then used to eject electrons from a metal surface whose work function is \(2.0\,\text{eV}\). Determine (a) the maximum kinetic energy of the emitted electrons and (b) the stopping potential required to halt them. Use the Rydberg constant \(R=1.097\times10^{7}\,\text{m}^{-1}\).

Answer Options

A. Maximum kinetic energy = 0.50 eV; Stopping potential = 0.50 V
B. Maximum kinetic energy = 0.66 eV; Stopping potential = 0.66 V
Correct Answer C. Maximum kinetic energy = 0.86 eV; Stopping potential = 0.86 V
D. Maximum kinetic energy = 1.00 eV; Stopping potential = 1.00 V
Correct Answer
C
Correct Option:
Maximum kinetic energy = 0.86 eV; Stopping potential = 0.86 V
