Motion in a Plane - Result Question 37
40. If a body $A$ of mass $M$ is thrown with velocity $v$ at an angle of $30^{\circ}$ to the horizontal and another body $B$ of the same mass is thrown with the same speed at an angle of $60^{\circ}$ to the horizontal, the ratio of horizontal range of $A$ to $B$ will be
[1992]
(a) $1: 3$
(b) $1: 1$
(c) $1: \sqrt{3}$
(d) $\sqrt{3}: 1$
Show Answer
