If two bodies are projected at 30⁰ and 60⁰ respectively with the same velocity, then

If two bodies are projected at 30⁰ and 60⁰ respectively with the same velocity, then

Options

(a) Their ranges are same
(b) Their heights are same
(c) Their times of flight are same
(d) All of these are same

Correct Answer:

Their ranges are same

Explanation:

Substituting θ in R=u²sin2θ/g
For 30° sin2θ => 60°
For 60° sin2θ => 120°
sin 120° = sin(180° − 120°) = √3/2
So Range is equal.
