Question

Two bodies of same mass are projected with the
same velocity at an angle 30° and 60° respectively.
The ratio of their horizontal ranges will be
(a) 1 : 1 (b) 1 : 2
(c) 1 : 3 (d) 2 : √2

Answer 1

Answer:

a 1:1

Explanation:

r = v^2 sin 2∅/g

sin 2 * 30 = sin 60 = $\frac{\sqrt{3} }{2}$

sin 2 * 60 = sin 120 = $\frac{\sqrt{3} }{2}$
