A) \[1.7\text{ }eV\]
B) \[3.4\text{ }eV\]
C) \[6.8\text{ }eV\]
D) \[13.6\text{ }eV\]
Correct Answer: B
Solution :
[b] Total energy in first excited state \[=-\frac{13.4}{4}=-3.4eV\] K.E. in first excited state = - total energy in that state \[=-(-3.4)=3.4\,eV\]You need to login to perform this action.
