A) \[6.63\times {{10}^{-35}}\,m\]
B) \[6.63\times {{10}^{-34}}\,m\]
C) \[6.65\times {{10}^{-33}}\,m\]
D) \[6.63\times {{10}^{-32}}\,m\]
Correct Answer: C
Solution :
\[\lambda =\frac{h}{mv}\]where \[\lambda =\]wavelength \[h=\]Planks constant \[=6.6\times {{10}^{-34}}\text{Js}\] \[m=mass={{10}^{-3}}\,kg\] \[v=100\] \[\lambda =\frac{6.6\times {{10}^{-34}}}{{{10}^{-3}}\times 100}\] \[=6.6\times {{10}^{-34}}\times {{10}^{1}}\] \[=6.6\times {{10}^{-33}}m.\]
