The De-Broglie wavelength associated with a particle of mass 1 mg moving with a velocity of `10ms^(-1)` is

Options

A. `6.63xx10^(-29)m`
B. `6.63xx10^(-31)m`
C. `6.63xx10^(-34)m`
D. `6.63xx10^(-22)m`

Answer

a

Explanation

Mass`, m=1m g=1xx10^(-6) kg`
Velocity,`v=10ms^(-1)`
`therefore` De-Broglie wavelength of a particle is given by ,
`lambda=h/(mv)=(6.625xx10^(-34))/(10^(-6)xx10)`
`=6.625xx10^(-29)m`
`=6.63xx10^(-29)m`
