Question

A radar observes an aeroplane moving horizontally with a velocity vat height h from ground. Ratio of angular acceleration to angular velocity of aeroplane, w.r.t. radar (in terms of v, h and theta) is

  1. fraction numerator v over denominator h end fraction sin to the power of 2 end exponent invisible function application theta    
  2. fraction numerator v over denominator h end fraction cos invisible function application 2 theta    
  3. fraction numerator v over denominator h end fraction cos to the power of 2 end exponent invisible function application theta    
  4. fraction numerator v over denominator h end fraction sin invisible function application 2 theta    

The correct answer is: fraction numerator v over denominator h end fraction sin invisible function application 2 theta
