扭秤实验装置是英国地质学家密歇耳首先发明的,借助绕着悬丝在水平方向的自由运动用以探测水平方向的相互作用,下面结合两道综合试题,感悟装置的制作精髓之处。【例1】图1是测量静电力恒量k的扭秤实验装置简图。两个极小的金属小球a、b通过一轻质杆用一细线悬挂起来,线上附有一面小镜子。另有一个极小的金属 The torsion scale experimental device was first invented by the British geologist Michel and was used to detect the interaction in the horizontal direction around the free movement of the suspension wire in the horizontal direction. The following combines two comprehensive test questions to comprehend the essence of the device’s production. . [Example 1] Fig. 1 is a schematic diagram of a torsion weigher experimental apparatus for measuring an electrostatic force constant k. The two tiny metal balls a, b are suspended by a thin wire with a thin wire and a small mirror is attached to the wire. Another tiny metal
