A projectile can have the same range R for two angles of projection. If t1 and t2 can be the times of flight in the two cases then what is the product of the two times of flight?
- \(t_1 t_2 \propto R^2\)
- \(t_1 t_2 \propto R\)
- \(t_1 t_2 \propto \frac{1}{ R}\)
- \(t_1 t_2 \propto \frac{1}{ R^2}\)
The Correct Option is B

Top Questions on projectile motion
A particle is projected at an angle of \( 30^\circ \) from horizontal at a speed of 60 m/s. The height traversed by the particle in the first second is \( h_0 \) and height traversed in the last second, before it reaches the maximum height, is \( h_1 \). The ratio \( \frac{h_0}{h_1} \) is __________. [Take \( g = 10 \, \text{m/s}^2 \)]
