A body of mass `10 mg` is moving with a velocity of `100 ms^(-1)`. The wavelength of the de Broglie wave associated with it would be

A

`6.63xx10^(-35)m`

B

`6.63xx10^(-31)m`

C

`6.63xx10^(-37)m`

D

`6.63xx10^(-34)m`

Text Solution

Verified by Experts

The correct Answer is:
B
`lambda=(h)/(m upsilon)=((6.626xx10^(-34)kgm^(2)s^(-1)))/((10xx10^(-6)kg)xx(100ms^(-1)))`
`=6.63xx10^(-31)m`.
