A through inclined is placed on car moving with a constant velocity u on horizontal ground . A block of mass M rests on the inclined plane . Is any work done by force of friction then a dissipation of energy ?

Text Solution

Verified by Experts

Yes , the friction ,
`f =Mg sin theta " " ( :. "M is at rest")`

Since , block is not in motion so , no work is done by the friction no dissipation of energy takes place.
