1. The problem statement, all variables and given/known data
If the left-hand slope in the figure makes a 60 degree angle with the horizontal, and the right-hand slope makes a 30 degree angle, how should the masses compare if the objects are not to slide along the frictionless slopes?

2. Relevant equations

besides degrees of the angles, I am stuck on how to go about the problem. Any hints is appreciated. =]

3. The attempt at a solution

Draw a free body diagram for each block.

Okay They are added. May you take a look and see if I am in the right direction?

Close, rewrite the forces in terms of their components parallel to and perpendicular to the slope. This leaves the normal forces only in the perpendicular directions, and the tension only in the parallel direction.
