Question

A uniform ladder of length 5m is placed against the wall as shown in the figure. If coefficient of friction m is the same for both the walls, what is the minimum value of mu for it not to slip?

  1. mu = 1/2    
  2. mu = 1/4    
  3. mu = 1/3    
  4. mu = 1/5    

The correct answer is: mu = 1/3
