Question

A small block is made to slide down on two slopes A and B one by one in two
different trials. Slope B is obtained by inverting the slope A about horizontal axis PQ. On each of the slopes, the block starts from rest at the top. Which of the following statement correctly describes motion of the block? [There is no friction anywhere]

(A) Speed at the bottom and time of descend are same on each slope A and B.
(B) Speed at the bottom is same on each slope but time of descend is smaller
on slope Athan on B.
(C) Speed at the bottom is same on each slope but time of descend is smaller
on slope B than on A.
(D) More information is required to decide.​
