a block of mass 4 kg rests on a instant plane of angle 30 degree with horizontal the coefficient of friction between surface in 0.5 what is the friction force act on a block

see figure for fbd
max force is 20N
max friction force = uN = 0.5 40 cos 30 = 20 root(3) /2
this friction is static that is self adjusting. so only 20 N friction is required to keep the object at relative rest,
