A body of mass 10 g is moving with a velocity of `100ms^(-1)`. The wavelength associated with it is

A

`6.63 xx 10^(-7) m`

B

`6.63 xx 10^(-31) m`

C

`6.63 xx 10^(-4) m`

D

`6.63 xx 10^(-35) m`

Text Solution

Verified by Experts

The correct Answer is:
B
`lambda = (h)/(mv) = (6.63 xx 10^(-34)kg m^(2) s^(-1))/((10 xx 10^(-6) kg) (100 m s^(-1)))`
`= 6.63 xx 10^(-31)m`
