For angles of projection of a projectile (45° − θ) and (45° + θ), the horizontal ranges described by the projectile are in the ratio

1. 1:3
2. 1:2
3. 2:1
4. 1:1

Correct answer: 1:1

Solution

The horizontal range of a projectile depends on the angle of projection and is symmetric about 45°. For angles (45° − θ) and (45° + θ), the ranges are equal, resulting in a ratio of 1:1.
