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

A

`1//100 cm`

B

`66 xx 10^(-34)m`

C

`1.32 xx 10^(-35) m`

D

`6.6 xx 10^(--26) m`

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda = (hc)/(mv) = (6.62 xx 10^(-34))/(0.5 xx 100) =1.6524 xx 10^(-34) xx 10^(-1)`
`= 1324 xx 10^(-35)m`
