Question

A person used force (f), shown in the figure to move a load with a constant velocity on a given surface.
Identify the correct sufface profile :

Options

A.
B.
C.
D.

Solution

In figure no.(a)and (c),a constant force equal to mg sin θ is required. After reaching the highest point, in case of figure (a), body travels on its own. So a -ve force is acting on the body. In this way, figure (a) represets the given F-x cure.
