Two objects are projected at an angle ^ and (90- ^ ) , to the horizontal with the same speed. The ratio of their maximum vertical heights is

Options

  1. A: 1
  2. B1:
  3. C^2 : 1
  4. D1: 1

Correct answer

C. ^2 : 1

Step-by-step solution

We know that, maximum vertical height in projectile motion, H= u^2 ^2 2 g [where, is angle of projection.] aligned & H ^2 & H₁ H₂ = ^2 ₁ ^2 ₂ = ^2 ^2(90- ) & [Given, . = and ₂=90^ - ] & = ^2 ^2 = ^2 & H₁: H₂= ^2 : 1 & aligned
