A) \[5\times {{10}^{-36}}kg,\,\,1.5\times {{10}^{-27}}\,kg\text{-}m/s\]
B) \[5\times {{10}^{-35}}kg,\,\,1.5\times {{10}^{-26}}kg\text{-}m/s\]
C) Zero, \[1.5\times {{10}^{-26}}\,kg\text{-}m/s\]
D) \[5\times {{10}^{-36}}kg,\,1.67\times {{10}^{-43}}kg\text{-}m/s\]
Correct Answer: A
Solution :
[a] \[p=\frac{h}{\lambda }=\frac{6.6\times {{10}^{-34}}}{4400\times {{10}^{-10}}}=1.5\times {{10}^{-27}}kg.m/s\] and mass \[m=\frac{p}{c}=\frac{1.5\times {{10}^{-27}}}{3\times {{10}^{8}}}=5\times {{10}^{-36}}kg\]
