A) \[3.3\times {{10}^{-29}}kg\ m/s\]
B) \[3.3\times {{10}^{-34}}kg\ m/s\]
C) \[6.6\times {{10}^{-34}}kg\ m/s\]
D) \[6.6\times {{10}^{-30}}kg\ m/s\]
Correct Answer: A
Solution :
\[p=\frac{h\nu }{c}=\frac{6.6\times {{10}^{-34}}\times 1.5\times {{10}^{13}}}{3\times {{10}^{8}}}\]\[=3.3\times {{10}^{-29}}kg\text{-}m/\sec \]
