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 sliding down the ramp at acceleration a. determine the apparent weight of the objects as it slides down. noth that there is friction between the object and the wedge so that the object remains relatively at rest on the wedge.

Options

A. `mg cos theta`
B. `mg cos^(2) theta`
C. `mg sin theta cos theta`
D. `mg tan theta`

Answer

B

Explanation

`N+mgsin^(2) theta=mg`
`N=mg cos^(2) theta`
