For angles of projection of projectile at angle (45^ - ) and (45^ + ) , the horizontal range described by the projectile are in the ratio of:

Options

  1. A2: 1
  2. B1: 1
  3. C2:3
  4. D1: 2

Correct answer

B. 1: 1

Step-by-step solution

Horizontal range =R= u^2 ^2 g When angle of projection is (45^ - ) then aligned R₁ & = u^2 2 (45^ - ) g & = u^2 (90^ - ) g & = u^2 2 g aligned Now R₁ R₂ = u^2 2 8 u^2 2 g =1: 1
