Two particles are projected from the same point with the same speed at different angles θ1 and θ2 to the horizontal. If their respective times of flights are T1 and T2 and horizontal ranges are same then
a) θ1+θ2 = 900 b) T1 = T2 tan θ1 c) T1 = T2 tan θ2 d) T1 sin θ2 = T2 sin θ1
Since ranges are same, θ1+ θ2 = 900
Now
Hence option -(1) is correct
