Question

Two racing cars of masses m1 and m2 are moving in circles of radii r1 and r2 respectively. Their speed are such that each makes a complete circle in the same duration of time t. The ratio of the angular speed of the first to the second car is :

  1. m1 : m2    
  2. r1 : r2    
  3. 1 : 1    
  4. m1r1 : m2r2    

The correct answer is: 1 : 1
