A) \[3.56\times {{10}^{-16}}\]
B) \[4.32\times {{10}^{22}}\]
C) \[2.01\times {{10}^{-24}}\]
D) \[3.12\times {{10}^{-28}}\]
Correct Answer: C
Solution :
According to de Broglie equation, \[\lambda =\frac{h}{p}\] where, p = momentum of electron \[\therefore \] \[p=\frac{h}{\lambda }=\frac{6.625\times {{10}^{-34}}}{0.33\times {{10}^{-9}}}\]\[=2.01\times {{10}^{-24}}kg\,m/\sec \]
