A projectile projected at an angle 30∘30^{{}^{\circ}} from the horizontal has a range R\mathrm{R}. If the angle of projection at the same initial velocity be 60∘60^{{}^{\circ}}, then the range will be-

Options

  1. AR\mathrm{R}
  2. BR/2\mathrm{R} / 2
  3. C2R2 \mathrm{R}
  4. DR2\mathrm{R}^{2}

Correct answer

A. R\mathrm{R}

Step-by-step solution

If sum of angle of projection =90∘=90^{{}^{\circ}} for given speed then range for that angle of projection is same.
