Wavelength of particle moving with momen...

Wavelength of particle moving with momentum `2xx10^(-28) kg ms^(-1)` will be ……

A

`3.3xx10^(-6)m`

B

`3.3xx10^(5)m`

C

`3.3xx10^(-4)m`

D

1.30 m

Text Solution

Verified by Experts

The correct Answer is:
A
de-Broglie wavelength of particle,
`lambda=(h)/(mv)=(h)/(p)`
`therefore lambda=(6.6xx10^(-34))/(2xx10^(-28))`
`therefore lambda=3.3xx10^(-6)m`
