Figure shows an irregular wedge of mass ...

Figure shows an irregular wedge of mass `m` placed on a smooth horizontal surface. Part `BC` is rough.
The magnitude of velocity of wedge when the block comes to rest `(w.r.t.` wedge `)` on part `BC` is `:`

A

`sqrt(gH)`

B

`sqrt(g(H-h))`

C

`2sqrt(gH)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
When the block comes to rest, the wedge continues to move at `V=(u)/(2)=sqrt(gH)` on the smooth surface. (since, momentum of wedge`-` block system remains conserved) .
