Please help calculate the reading of the spring scale

Question 1 (10 points) Listen The horizontal uniform rod shown has length 0.60 m and mass 2.0 kg. The left end of the rod is attached to a vertical support by a frictionless hinge that allows the rod to swing up or down. The right end of the rod is supported by a cord that makes an angle of 300 with the rod. A spring scale of negligible mass measures the tension in the cord. A 0.50 kg block is also attached to the right end of the rod. Spring scale 30 Hinge S 2.0 kg. 0.50 kg 0.60 m
