where 
is the ground state energy. If 
is the angular momentum of the electron in this orbit and 
is the Planck's constant, then 
is 
:
Text Solution
Verified by ExpertsThe correct answer is:
A
In Bohr's atom, the energy levels are 
where 
is the ground state energy.
Given 
, we have 
, which gives 
, so 
.
The angular momentum in Bohr's model is 
.
Therefore, 
.
