A particle of mass m is projected form ground with velocity u making angle `theta` with the vertical. The de Broglie wavelength of the particle at the highest point is

A

`oo`

B

`h/(m u sin theta)`

C

`h/(m u cos theta)`

D

`h/(m u)`

Text Solution

Verified by Experts

The correct Answer is:
B
Velocity at highest point `=u sin theta`
`:. lambda_(D)=h/(m u sin theta)` (since `theta` is velocity w.r.t vertical)
