A) \[2.2\times {{10}^{-27}}cm\]
B) \[1.104\times {{10}^{-32}}cm\]
C) \[1.104\times {{10}^{-32}}cm\]
D) \[1.104\times {{10}^{-33}}cm\]
Correct Answer: B
Solution :
Given,\[m=200\,\,g,\,\,v=3\times {{10}^{3}}cm/s\] \[h=6.624\times {{10}^{-27}}erg\,\,s,\lambda =?\] \[\lambda =\frac{h}{mv}=\frac{6.624\times {{10}^{-27}}}{200\times 3\times {{10}^{3}}}\] \[\therefore \] \[\lambda =1.104\times {{10}^{-32}}cm\]
