Atomic Structure Question 175
Question: A 200g golf ball is moving with a speed of 5 m per hour. The associated wave length is $ (h=6.625\times {10^{-34}}J\text{-}sec) $
Options:
A) $ {10^{-10}},m $
B) $ {10^{-20}},m $
C) $ {10^{-30}},m $
D) $ {10^{-40}},m $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \lambda =\frac{h}{mv}=\frac{6.625\times {10^{-34}}}{0.2,kg\times \frac{5}{60\times 60,m{s^{-1}}}}={10^{-30}}m $ .
