the mass of triangular block B is 10 kg. the coefficient of friction between A and B is 0.1 and that between triangular block B and ground is 0.4 .the maximum value of mass of block A ,so that system remains in equilibrium is?

Dear Student,

Thank you for sharing your query with us. 
Your question is not clear and appears to be incomplete. There is no information regarding the triangular block B i.e what type of a triangle it is, Even if we assume that it is a standard right triangular wedge, then also we need the angle of inclination of the wedge as all forces on block A, be it friction or gravity would depend on the angle of inclination of the wedge.

I thus request you to ask the question again in a new thread, and please be a little specific so that we can provide you with rapid assistance and some meaningful help.

Looking forward to hearing from you again!
