A) \[6.63\times {{10}^{-7}}\]
B) \[6.63\times {{10}^{-16}}\]
C) \[6.63\times {{10}^{-21}}\]
D) \[6.63\times {{10}^{-29}}\]
Correct Answer: D
Solution :
Key Idea: According to de-Broglie, the relationship between wavelength and momentum mv of subatomic particle is \[\lambda =\frac{h}{mv}\] \[\lambda =\frac{6.63\times {{10}^{-34}}}{{{10}^{-6}}\times 10}=6.63\times {{10}^{29}}\]
