Two projectiles are fired with same initial speed from same point on ground at angles of (45° – α ) and (45° + α ), respectively, with the horizontal direction. The ratio of their maximum heights attained is :

1. α + α − tan 1 tan 1
2. α − α + sin 1 sin 1
3. α + α − 2 sin 1 2 sin 1
4. α − α + 2 sin 1 2 sin 1

Correct answer: α + α − 2 sin 1 2 sin 1
