A) \[4\overset{\text{o}}{\mathop{\text{A}}}\,\]
B) \[4\,\,nm\]
C) \[16\,\,\overset{\text{o}}{\mathop{\text{A}}}\,\]
D) \[16\,\,nm\]
Correct Answer: C
Solution :
According to Bohrs postulate and de-Broglie equation \[2\pi r=n\lambda \] Here, \[2\pi r=\]circumference of the orbit \[n=4\] \[\lambda =4\overset{\text{o}}{\mathop{\text{A}}}\,\] \[\therefore \] \[2\pi r=4\times 4\] \[=16\overset{\text{o}}{\mathop{\text{A}}}\,\]You need to login to perform this action.
