Physics - NLM Question with Solution | TestHub

An inclined plane is fitted within an elevator, and a block of mass 'm' is allowed to slide down the plane starting from rest. The block takes a time T to reach the bottom of the plane. If the elevator descends with an acceleration a $(\mathrm{a}<\mathrm{g})$,the time taken by the same block to slide down the plane starting from the same position is ${\mathrm{T}}^{\wedge }$. Then
