What force must be applied to the rope so that the mass stays at rest?
2. Homework Equations
Fnet = ma.....
3. The Attempt at a Solution
I am really clueless when it comes to this question. I know the net force must be 0 because there is no acceleration occuring b/c it must be at rest. Please help.
