The wavelength of electron in ground sta...

The wavelength of electron in ground state is `2.116Å`, then its momentum will be ......

A

`313gcms^(-1)`

B

`313kgms^(-1)`

C

`3.13xx10^(-24)gcms^(-1)`

D

`3.13xx10^(-24)kgms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`lamda=(h)/(p)=(6.62xx10^(-34))/(2.116xx10^(-10))`
`=3.1285xx10^(-24)=3.13xx10^(-24)kgms^(-1)`
