Second law

Suppose the box $A$ is in equilibrium (at rest) in the position illustrated below when a force $F$ is applied at the cable. Box $A$ has mass $M_A = 8$ kg. Assume gravity equals to $10 \rm m / s^2$. Assume frictionless pulley. Determine the force in the cable required for this equilibrium configuration.
