A projectile can have the same range 'R' for two angles of projection. If 'T₁' and 'T₂' be the time of flights in the two cases, then the product of the two times of flights is directly proportional to

1. R
2. 1/R
3. 1/R²
4. R²

Correct answer: R

Solution

The time of flight for a projectile is influenced by the range and the angle of projection. When two angles yield the same range, the product of their respective times of flight is directly proportional to the range itself, as derived from the equations of motion for projectile motion.
