de-Broglie wavelength of a body of mass ...

de-Broglie wavelength of a body of mass 1 kg moving with velocity of 2000 m/s is

A

`3.32xx10^(-27) Å`

B

`1.5xx10^(7) Å`

C

`0.55xx10^(-22) Å`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda=h/(mv)=(6.63xx10^(-34))/(1xx2xx10^(-3))`
`=3.3xx10^(-37)=3.3xx10^(-27) Å`
