A block 'A' takes $\displaystyle 2$ s to slide down a frictionless incline of $\displaystyle 30$° and length ' $\displaystyle l$ ', kept inside a lift going up with uniform velocity ' $\displaystyle v$ '. If the incline is changed to $\displaystyle 45^{\circ}$, the time taken by the block, to slide down the incline, will be approximately :
Official answer
(3)
1.$\displaystyle 68$ s
