MCQ

A homogeneous cubical brick lies motionless on a rough inclined surface. The half of the brick which applies greater pressure on the plane is :

✓
left half
B
right half
C
both applies equal pressure
D
the answer depend upon coefficient of friction

✓

Answer

Correct option: A.

left half

a
If we draw an $FBD$ of this brick we see that the force exerted by the right part on the left part has a component in downward direction and that exerted by the left part on the right part is in the upward direction. Thus we see that the left part exerts more pressure on the plane.
