Two projectiles thrown from the same point at angles60^(@)and 30^(@)wi

1.	Two projectiles thrown from the same point at angles60^(@)and 30^(@)with the horizontal attain the same height . Which of the following statements is a correct statement ?
Answer» The ratio of their initial velocityies is`sqrt(3)` The ratio of their initial velocities is`(1)/(sqrt(3))` The ratio of their initial velocities is 1. The ratio of their initial velocities is infinity . SOLUTION :`h_("MAX") = (u^(2) sin^(2) theta)/(2g)` `h_("max")`is same in both the cases . `u_(1)^(2) sin^(2)30^(@)` `(u_(1))/(u_(2)) = (sin 30^(@))/(sin 60^(@))` `= (1)/(2) XX (2)/(sqrt(3)) = (1)/(sqrt(3))`
