A) \[1.3\times {{10}^{-27}}kg\text{-}\]m/sec
B) \[1.3\times {{10}^{-28}}kg\text{-}\]m/sec
C) \[4\times {{10}^{29}}kg\text{-}\]m/sec
D) \[4\times {{10}^{-18}}kg\text{-}\]m/sec
Correct Answer: A
Solution :
\[p=\frac{h}{\lambda }\]\[=\frac{6.6\times {{10}^{-34}}}{(5000\times {{10}^{-10}})}=1.3\times {{10}^{-27}}kg\text{-}m/s\]
