A box is moving upward with retardation ...

A box is moving upward with retardation 'a'`lt g `, find the direction and magnitude of "pseudo force " acting on block of mass 'm' placed inside the box.Also calculate normal force exerted by surface on block

Text Solution

Verified by Experts

Pseudo force acts opposite to the direction of acceleration of reference frame.
pseudo force = ma in upward direction

F.B.D of 'm' w.r.t box (non-inertial)
