A block of mass m is kept on a wedge of mass M as shown in figure such that mass m remains stationary w.r.t wedge. The magnitude of force P is A block of mass m, is kept on a wedge of mass M as shown in figure such that mass m remains stationary w.r.t. wedge. The magnitude of force P is (1) g tan ß (3) (m + M)g tan ß (2) mg tan (4) mg cot ß

It's my 1st and. On meritanation hope it will help u

a=FM+ma=FM+m
ΣFy=0=>Ncosθ=mgΣFy=0=>Ncos⁡θ=mg
ΣFx=0=>Nsinθ=maΣFx=0=>Nsin⁡θ=ma
a=gtanθa=gtan⁡θ
F=a(M+m)F=a(M+m)
=gtanθ(M+m)
