Question

A body is in pure rotation. The linear speed  of a particle, the distance r of the particle from the axis and the angular velocity  of the body are related as  = fraction numerator v over denominator r end fraction. Thus-

  1. fraction numerator 1 over denominator r end fraction  
  2.  r  
  3.  = 0  
  4.  is independent of r.  

The correct answer is:  is independent of r.
