A) \[6.626\times {{10}^{-34}}\operatorname{m}\]
B) \[6.626\times {{10}^{-38}}\operatorname{m}\]
C) \[6.626\times {{10}^{-31}}\operatorname{m}\]
D) \[6.626\times {{10}^{-30}}\operatorname{m}\]
Correct Answer: B
Solution :
\[\lambda =\frac{h}{mv}\] \[h=6.6\times {{10}^{-34}}J/s\] \[m=1000kg\] \[v=36km/hr=\frac{36\times {{10}^{3}}}{60\times 60}m/\sec =10m/\sec \] \[\therefore \]\[\lambda =\frac{6.6\times {{10}^{-34}}}{{{10}^{3}}\times 10}=6.6\times {{10}^{-38}}m\]
