Let a rectangle having the diagonal length `sqrt5` is given as shown in the figure. First time it is rotated along the side x to make a cylinder & then again it is rotated along the side y to make another cylinder The maximum difference between volumes of both the cylinders occurs when xy is equal to: (1) `4/9` (2) `9/4` (3) `5/3` (4) `3/5`
