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