Two bodies X and Y are projected on the same horizontal plane, with the same initial speed but at angles 30 and 60 respectively to the horizontal. Neglecting air resistance, the ratio of the range of X to that of Y is

sin 2 x 30
—————. = 0.8660/0.8660
sin 2 x 60

=1/1
ratio=1:1

x : y = x/y
= U^2sin60/U^sin120
U^2 will cancel U^2 leaving us with
Sin60/sin120
Sin60 = 0.8660
Sin120 = 0.8660
Therefore ans = 1/1 A

sin60=((3)^1/2 /2) sin120=1/2
3^1/2 :1
