Velocity of particle having 1 mg mass is...

Velocity of particle having 1 mg mass is 72 km/hr.Its de-Broglie wavelength is ….

A

`3.3xx10^(-29)`

B

`3.3xx10^(-10)`

C

`3.3xx10^(-32)`

D

`3.3xx10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
A
`m=10^(-6)` kg
`v=(72xx1000)/(3600)(m)/(s)` de-Broglie wavelength of particle ,
`lambda=(h)/(p)=(h)/(mv)`
`therefore lambda=(6.6xx10^(-34))/(10^(-6)xx20)`
`therefore lambda=3.3xx10^(-29)m`
