A track (ACB) is in the shape of an arc of a circle. It is held fixed in vertical plane with its radius OA horizontal. A small block is released on the inner surface of the track from point A. It slides without friction and leaves the track at B. What should be value of q so that the block travels the largest horizontal distance by the time it returns to the horizontal plane passing through B?
