I think your question should have read, "..what is the net torque...?". In which case the net torque is the sum of the torques from each force , that is, Tnet = r1 X F1 + r2 X F2, where the direction of each torque (positive or negative) depends upon whether each torque is acting counterclockwise or clockwise about that fixed point.

The net force is simple the sum of the two forces. To determine the signs of the forces you must determine the direction the force is moving, either counterclockwise or clockwise. If clockwise the force is negative, and if counterclockwise the force is positive. Once you have determined the signs of the forces you simple add them together and you have your net torque.
