As shown in the figure, a wedge of mass \( M \) is placed on a smooth inclined ramp that makes an angle \( \theta \) to the horizontal. An object of mass \( m \) rests on top of the wedge. The system is sliding down the ramp at acceleration a. Determine the apparent weight of the object as it slides down. Note that there is friction between the object and the wedge so that the object remains relatively at rest on the wedge.
(a) \( m g \cos \theta \)
(b) \( m g \cos ^{2} \theta \)
(c) \( m g \sin \theta \cos \theta \)
(d) \( m g \tan \theta \)
