In the 1988 college entrance examination physics experiment question 2, the original title was: There is a tray balance, there is no tour code, the minimum weight is 100 mg. Use this scale to weigh an object. When a 36.20-g weight is added to the right-hand disk, the balance hand is shifted to the left by 1.0 square, as shown by the solid arrow in Figure 1, and 100 mg is added to the right-hand disk. Code, balance pointer to the right side of 1.5 small grid. As shown by the dotted arrow in Figure 1. The mass of this object can be read as ____ grams. Admission _· Consultation 1. .11 This problem is not difficult, as long as the knowledge that you have learned is used flexibly, this question can be answered successfully.
