A box weighing 68 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end.Determine the force that the table exerts on the box when weight hanging on the other side of the pulley is 27N.

2. Relevant equations

laws of motion

3. The attempt at a solution

draw free body diagram, fillin law, mg=27n

i have 2 divide mg by g to get m since the box does not move yet its accleration is 0 so mg = Fn? ?? except tension plays a role so how do i find Fn-Ft=mg?
