[AIIMS 2001]
Options:
A) $ 6.63\times {10^{-22}}m $
B) $ 6.63\times {10^{-29}},m $
C) $ 6.63\times {10^{-31}},m $
D) $ 6.63\times {10^{-34}},m $
Show Answer
Answer:
Correct Answer: B
Solution:
Mass of the particle $ (m)={10^{-6}} $ kg and velocity of the particle $ (v)=10,m{s^{-1}} $
$ \lambda =\frac{h}{mv}=\frac{6.63\times {10^{-34}}}{{10^{-6}}\times 10}=6.63\times {10^{-29}}m $
