Question

A solid sphere is in pure rolling motion on an inclined surface having inclination theta :

  1. frictional force acting on sphere is f equals mu m g c o s invisible function application theta    
  2. f is dissipative force    
  3. friction will increase its angular velocity and decreases its linear velocity    
  4. if theta decrease, friction will decrease    

The correct answer is: friction will increase its angular velocity and decreases its linear velocity
