PhysicsMotion in a PlaneJEE Main

Two bodies are projected from the same point with equal speeds in such directions that they both strike the same point on a plane whose inclination is . If is the angle of projection of the first body with the horizontal, the ratio of their times of flight is

Answer: (C)

Solution

Let be the angle of projection of the second body. Since both have the same range on the inclined plane, $(2α-β) = (2α''-β) ⇒ α'' =
