A particle (1) is projected with speed V from a point O making an angle of 30o with the vertical. At the same instant, a second particle (2) is thrown vertically upwards with velocity v from a point A. The two particles reach H, the highest point on the parabolic path of particle (1) simultaneously. The ratio of V/v is
Time taken by particle 1 to reach H is given by
Time taken by particle 2 reach H is given by
Now
