Questions
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
detailed solution
Correct option is A
Time taken by particle 1 to reach H is given byt=Vsin60∘g=3V2gTime taken by particle 2 reach H is given byt′=vgNow 3V2g=vg or Vv=23Similar Questions
Assertion : When the velocity of projection of a body is made n times, its time of flight becomes n times.
Reason : Range of projectile does not depend on the initial velocity of a body.
