The coeff of friction b/w the block A of mass m and triangular wedge B of mass M is @. There is no friction b/w the wedge and the plane. If the system (blockA + wedge B) is released so that there is no sliding b/w A and B, show that the max possible inclination theta is equals to tan -1 @.

							 hi,


if  there no frctn b/n B & PLANE
      then, accelrn  of (A+B) wud be g sin(theta). along the plne indwnward diectn,


now cosider the A w.r.t B forces on A    1) psuedo f = m* gsin(theta) upward along th pln
                                         2) gravity = mg vertical dwnwrd
                                         3)max. friction force = @*{mg-mg sin^2(theta)}  
                                          
                                        mg sin^2(theta) is vertical compnent of psuedo f   
                                
                                       {mg-mg sin^2(theta)} = total dwn force 
          
                                       horizontal comp of psuedo f = mg*sin(theta)* cos(theta)
                                
 now in limiting case max frctn f = mg cos^2(theta)
  
=>  @*mg {1- sin^2(theta)}=mg*sin(theta)*cos(theta)
 => @ = tan(theta)                                     
   =>  theta = tan^-1@.
