Question

Two projectiles thrown at same speed u at angles (45° + α) and (45° − α). Their ranges are:
  1. A
    Equal
    Correct
  2. B
    Differ by 2α
  3. C
    In ratio sinα:cosα
  4. D
    Unequal

Correct answer

Equal

Explanation

R₁ = u²sin(90°+2α)/g = u²cos2α/g. R₂ = u²sin(90°−2α)/g = u²cos2α/g. Both ranges are equal.
