In the diagram illustrated a block of mass M is at rest on a plane inclined at an angle θ to the horizontal. As θ increases, the velocity ratio of the plane
A.
increases
B.
decreases
C.
remain the same
D.
decreases and later increases
Correct answer is B
The velocity ratio and therefore, the mechanical advantage of an inclined plane system increases as θ decreases and vice-versa.
