Dear Vijay,

Ans:- Whether The surface is smooth or rough it would not matter,  the value of the mass  can not be calculated because it would become mass independent. Because if the wedge is moving with an acc..n  then the pseudo force will become ma i.e mass dependent hence in every eq the mass value would cancell out So, the value of the mass can not be calculated
