The electron in the hydrogen atom jumps from excited state 
to its ground state 
and the photons thus emitted irradiate a photosensitive material. If the work function of the material is 5.1 
the stopping potential is estimated to be (the energy of the electron in 
state 
Text Solution
Verified by ExpertsThe correct answer is:
D
Energy released when electron in the atom jumps from excited state 
to ground state 
is
Therefore, stopping potential
[ work function 
]
