Atomic Structure Question 176

Question: A cricket ball of $ 0.5,kg $ is moving with a velocity of $ 100,m/\sec $ . The wavelength associated with its motion is [DCE 2004]

Options:

A) $ 1/100cm $

B) $ 6.6\times {10^{-34}}m $

C) $ 1.32\times {10^{-35}}m $

D) $ 6.6\times {10^{-28}}m $

Show Answer

Answer:

Correct Answer: C

Solution:

From de Broglie equation $ \lambda =\frac{h}{mv} $ = $ \frac{6.62\times {10^{-34}}}{0.5\times 100} $ = $ 1.32\times {10^{-35}}m $ .
