A cricket ball of `0.5kg` moving with a velocity of `100 m s^(-1)`. The wavelength associated with its motion is

Options

A. `1//100 cm`
B. `66 xx 10^-34 m`
C. `1.32 xx 10^-35 m`
D. `6.6 xx 10^-28 m`

Answer

C

Explanation

`lamda = (h)/(mv) = (6.62 xx 10^-34)/(0.5 xx 100) = 1.324 xx 10^-34 xx 10^-1`
=`1.324 xx 10^-35 m`.
