Question

The horizontal range of a projectile 4 square root of 3 times the maximum height achieved by it, then the angle of projection is

  1. 30 degree    
  2. 45 degree    
  3. 60 degree    
  4. 90 degree    

The correct answer is: 30 degree


    fraction numerator u to the power of 2 end exponent sin invisible function application 2 theta over denominator g end fraction equals 4 square root of 3 cross times fraction numerator u to the power of 2 end exponent sin invisible function application theta over denominator 2 g end fraction
    or fraction numerator u to the power of 2 end exponent over denominator g end fraction 2 sin invisible function application theta cos invisible function application theta equals 2 square root of 3 fraction numerator u to the power of 2 end exponent over denominator g end fraction sin to the power of 2 end exponent invisible function application theta
