A projectile can have the same range ‘R’ for two angles of projection. If ‘T1 ’ and ‘T2 ’ be time of flights in the two cases, then the product of the two time of flights is directly proportional to
(a) R
(b) 1/R
(c) 1/R2
(d) R2
Correct option (a) R
Explanation:
The angle for which the ranges are same is complementary.
Let one angle be θ, then other is 90° – θ
Hence it is proportional to R.
