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

\beta

. If 

\alpha

be the angle of projection of the first body with the horizontal the ratio of their times of flight is

View answer and explanation

Correct option: D

\frac{{\sin \left( {\mathrm{\alpha } - \mathrm{\beta }} \right)}}{{\cos \mathrm{\alpha }}}

Option D (

\frac{{\sin \left( {\alpha - \beta } \right)}}{{\cos \alpha }}

) is correct because it represents the ratio of the times of flight derived from the range equation on an inclined plane.
