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.
