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

A

`2.126xx10^(-23) kg ms^(-1)`

B

`6.626xx10^(-22) kg ms^(-1)`

C

`3.456xx10^(-25) kg ms^(-1)`

D

`3.313xx10^(-22) kg ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`p=(h)/(lambda)=(6.6xx10^(-34))/(0.01xx10^(-10))=6.626xx10^(-22)"kg ms"^(-1)`
