A) \[{{10}^{-33}}\] m
B) \[{{10}^{-31}}\] m
C) \[{{10}^{-16}}\]m
D) \[{{10}^{-25}}\] m
Correct Answer: A
Solution :
\[\lambda =\frac{h}{mv}\] Given, \[h=6.63\times {{10}^{-34}}Js\] or \[h=6.63\times {{10}^{-34}}kg\,{{m}^{2}}{{s}^{-1}}\] \[(\therefore J=kg\,{{m}^{2}}{{s}^{-2}})\] or \[h=6.63\times {{10}^{-31}}g\,{{m}^{2}}{{s}^{-1}}\] m = 60g v = 10m/s Thus \[\lambda =\frac{6.63\times {{10}^{-31}}}{60\times 10}\] \[=1.105\times {{10}^{-33}}m\]
