1988年高考物理试题第(2)道实验题延拓于课本习题,又颇具新意,既能考查基础知识又能考查学生测量技能,确是一道比较好的试题。原题是:“有一架托盘天平,最小砝码为100毫克。用这架天平称量一个物体,当右盘中加上36.20克砝码时,天平指针向左偏1.0小格,如图1中实线箭头所示。如果在 In the 1988 college entrance examination physics test question (2), the experiment was extended to textbook exercises. It was also quite innovative. It was a good test to examine both the basic knowledge and the measurement skills of students. The original question is: "There is a tray balance, the minimum weight is 100 mg. Use this scale to weigh an object. When you add 36.20 gram weights to the right disk, the balance pointer is shifted to the left by 1.0, as shown in Figure 1. The solid line arrow shows if
