Question
a wedge of mass M' is connected with a hanging block of mass M with a light string and a massless pulley. and a small block of mass m is placed on the top of te wedge. find the mass M of the hanging block which will prevent the smaller block from slipping over the wedge . All the surfaces are smooth .

According to the given diagram Mg - T = Ma, T = (M'+m)a and macosθ = mgsinθ
solve these equations.
