Two projectiles A and B are projected with the same initial speed, at 1 5 ∘ for A and 4 5 ∘ for B . If R A and R B are their horizontal ranges, then:

With equal speeds, R ∝ sin 2 θ : sin 3 0 ∘ < sin 9 0 ∘ , so R A < R B . Option A.

Two projectiles $A$ and $B$ are projected with the same initial speed, at $1 5^{\circ}$ for $A$ and $4 5^{\circ}$ for $B$ . If $R_{A}$ and $R_{B}$ are their horizontal ranges, then:

Options:

Answer:

Solution:

With equal speeds, $R \propto sin 2 θ$ : $sin 3 0^{\circ} < sin 9 0^{\circ}$ , so $R_{A} < R_{B}$ . Option A.
