A) \[6.63\times {{10}^{-35}}m\]
B) \[6.63\times {{10}^{-34}}m\]
C) \[6.63\times {{10}^{-31}}m\]
D) \[6.63\times {{10}^{-37}}m\]
Correct Answer: C
Solution :
\[m=10\,mg=10\times {{10}^{-6}}\,g\] \[v=100\,\,m{{s}^{-1}}\] \[\lambda =\frac{h}{mv}=\frac{6.63\times {{10}^{-34}}}{10\times {{10}^{-6}}\times 100}\] \[=6..63\times {{10}^{-31}}m\]
