Question
The particle P & Q are projected simultaneously from a point O on a level ground in the same vertical plane with the same speed in direction making angle of 30o and 60o respectively with the horizontal
Options
A.Both reach the ground simultaneously
B.Preaches the ground earlier than Q
C.Both strike the same point on the level ground
D.The maximum height attained by Q in thrice that attained by P
Solution
Range = 
For θ & (90 - θ) angles, range will be same so for 30o & (90 - 30o) 60o, projections both strike at the same point. For time of flight, vertical components are responsible
