The horizontal range and the maximum height of a projectile are equal. The angle of projection of the projectile is

Options

  1. A= ⁻¹ ( 1 4 )
  2. B= ⁻¹(4)
  3. C= ⁻¹(2)
  4. D=45^

Correct answer

B. = ⁻¹(4)

Step-by-step solution

Given, R=H Range R= u^2(2 ) g Height H= u^2 ^2 2 g Hence, u^2(2 ) g = u^2 ^2 a 2 g aligned 2 & = 2 & =4 & = ⁻¹(4) aligned
