If the de-Broglie wavelength of a particle of mass m is 100 times its velocity then its value in terms of its mass (m) and Planck's constant (h) is

A

`1/10sqrt(m/h)`

B

`10sqrt(h/m)`

C

`1/10sqrt(h/m)`

D

`10sqrt(m/h)`

Text Solution

Verified by Experts

The correct Answer is:
B
Let wavelength of particle be `chi`
So velocity = `chi/100`
`lamda=h/(mv),chi=(hxx100)/(mxxchi)`
`chi^(2)=100h/morchi=10sqrt(h/m)`.
