Question

In figure, two blocks M and m are tied together with an inextensible and light string. The mass M is placed on a rough horizontal surface with coefficient of friction mu and the mass m is hanging vertically against a smooth vertical wall. The pulley is frictionless. Choose the correct statement(s) related to the tension T in the string

  1. When m < muM, T = mg    
  2. When m < muM, T = Mg    
  3. When m > muM, muMg < T < mg    
  4. When m > muM, mg < T < muMg    

The correct answer is: When m > muM, muMg < T < mg
