A dust particle of mass 2 mg is carried by wind with a velocity of 100 cm/s. What is the de-Broglie wavelength associated with the dust particle? (`h = 6.63 xx 10^(-34) J-s`)

A

`3.32xx10^(-31) m`

B

`6.64xx10^(-30) m`

C

`3.32xx10^(-34) m`

D

`3.32 xx10^(-28) m`

Text Solution

Verified by Experts

The correct Answer is:
D
`lambda=h/(mv)=(6.63xx10^(-34))/(2xx10^(-3) xx1)=3.3xx10^(-28) m`
