A body of mass x kg is moving with a velocity of `100ms^(-1)` . Its de-Broglie wavelength is `6.62xx10^(-35)m` . Hence, x is: `(h=6.62xx10^(-34)Js)`

Text Solution

Verified by Experts

The correct Answer is:
`0.1`
`lamda=h/(mv)`
`:. m =(h)/(lamdaxxv)=(6.62 xx10^(-34)Js)/((6.62 xx10^(-35)m)(100 ms^(-1)))=0.1 `kg
