Chemistry Question on Structure of atom

The de-Broglie wavelength of a tennis ball of mass 60 g60\, g moving with a velocity of 10m/s10 m / s is approximately : (Planck's constant, h=6.63×10−34 Jsh=6.63 \times 10^{-34} \,Js )

A

10−33 m10^{-33}\, m

B

10−31 m10^{-31} \,m

C

10−16 m10^{-16} \,m

D

10−25 m10^{-25} \,m

Answer

10−33 m10^{-33}\, m

Explanation

Solution

λ=hmv=1.105×10−33 m\lambda=\frac{h}{m v}=1.105 \times 10^{-33} \,m
