A wedge m of weight 104 N is sliding on a smooth inclined plane of an elevator which is moving down with a constant acceleration 'f = 2 m/s2' as shown in the figure. What will be the net normal reaction force acting on the wedge exerted by the inclined plane of an elevator? Take g = 10 m/s2. The inclination angle of the lift plane 30°.
