· 3. A wedge of mass 2m is kept on a rough horizontal floor and is always stationary. A block of mass m is kept on the smooth surface of wedge and is held stationary by a stopper. The Incline plane of the wedge makes an angle e with horizontal. Stopper 2m Rough (A) When the stopper is removed, the normal reaction the floor exerts on the wedge is N = mg (2+cos*e) (B) When the stopper is removed, the nomal reaction the floor exerts on the wedge is N = mg (2+sinecos8) (C) Whether stopper is removed or not, the normal reaction the floor exerts on the wedge is N= 3mg (D) When the stopper is removed, the frictional force between the wedge and the floor is mgcose.sine
