Vedclass · Answer

(A) Consider the block of mass $m$ on the inclined plane inside the lift.When the lift is descending with a downward acceleration $a$,a pseudo force $F_p = ma$ acts on the block in the upward direction.The effective gravitational acceleration experienced by the block in the frame of the lift is $g_{eff} = g - a$ (downward).The component of this effective acceleration along the inclined plane is $a_{rel} = g_{eff} \sin 	heta$.Substituting $g_{eff}$,we get $a_{rel} = (g - a) \sin 	heta$.

$A$ block can slide on a smooth inclined plane of inclination $\theta$ kept on the floor of a lift. When the lift is descending with an acceleration $a$,the acceleration of the block relative to the incline is:
