(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Small block of mass "m" rests on sloping side of triangular block of mass "M" which itself rests on table. Assuming all surfaces arefrictionless, determine force "F" that must be applied to "M" so that "m" remains fixed. Wedge incline is "THETA"

2. Relevant equations

3. The attempt at a solution

attached is picture. I don't know where to start, so no attempted solution. The answer is:

F = (m+M)g*tan(THETA). i don't see why the mass on the wedge would move up the ramp if a force is applied to the left of the wedge.

where g is acceleration due to gravity
