Two projectiles A and B are projected with angle of projection 15° for the projectile A and 45° for the projectile B,
Two projectiles A and B are projected with angle of projection 15° for the projectile A and 45° for the projectile B. If RA and RB be the horizontal range for the two projectiles, then
(a) RA < RB
(b) RA = RB
(c) RA > RB
(d) the information is insufficient to decide the relation of RA with RB.

(d) the information is insufficient to decide the relation of RA with RB.
Explanation:
The range of a projectile depends upon the projected velocity and the angle of projection as is clear from the formula R= (u2 /g) Sin2θ
But in this question only angle of projection is given, not the projected velocity.
