A) 1
B) 2
C) 3
D) 4
Correct Answer: D
Solution :
\[n{{\beta }_{1}}\,\,=\,(n+1){{\beta }_{2}}\] \[\Rightarrow \,\,\,\frac{n\times 650\times {{10}^{-19}}D\,}{d}\,\,=\,\,\,\frac{(n+1)\,\times 520\times {{10}^{\text{-}19}}\times \,\,D}{d}\] \[\Rightarrow \,\,n=4\]You need to login to perform this action.
