A) \[7.25\times {{10}^{6}}\,m/s\]
B) \[6.26\times {{10}^{6}}\,m/s\]
C) \[5.25\times {{10}^{6}}\,m/s\]
D) \[4.24\times {{10}^{6}}\,m/s\]
Correct Answer: A
Solution :
\[v=\frac{p}{m}=\frac{h}{m\lambda }=\frac{6.6\times {{10}^{-34}}}{9.1\times {{10}^{-31}}\times {{10}^{-10}}}=7.25\times {{10}^{6}}\ m/s\]You need to login to perform this action.
