A body of mass x kg is moving with a velocity of 100 m/s.Its de Broglie wavelength is `6.62xx10^(-35)`m . Hencex is`[h=6.2xx10^(-34)Js]`

A

`0.25 kg`

B

`0.15 kg`

C

`0.2 kg`

D

`0.1 kg`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=h/(mv)`
`m=h/(lamdav)=(6.62xx10^(-34))/(6.62xx10^(-35)xx100)=0.1kg`
