An X-ray has wavelength of `0.010Å`. Its momentum is

A

`2.126 xx10^(-23) kg-m//s`

B

`6.626 xx10^(-22) kg-m//s`

C

`3.456 xx10^(-25) kg-m//s`

D

`3.313 xx10^(-22) kg-m//s`

Text Solution

Verified by Experts

The correct Answer is:

B

`lamda=h/pimpliesh/lamda=(6.6 xx10^(-34))/(0.01 xx10^(-10))=6.6xx10^(-22)kgm//sec `
