1. The problem statement, all variables and given/known data FC of magnitude 188 N. Note that the direction of FC is not given. What is the magnitude of Betty's force FB if Charles pulls in (a) the direction drawn in the picture or (b) the other possible direction for equilibrium 2. Relevant equations ΣF=0 3. The attempt at a solution Im having trouble with part b) of the question. I dont know what other possiblities there are.
