今年高考物理实验试题是教科书上的二个学生实验·原题如下:22、(17分)(1)在“验证力的平行四边形定则”实验中,需要将橡皮条的一端固定在水平木板上,另一端系上两根细绳,细绳的另一端都有绳套(如图1)·实验中需用两个弹簧秤分别勾住绳套,并互成角度地拉橡皮条·某同学认为此过 This year’s college entrance examination physics test questions are two student experiments in textbooks. The original questions are as follows: 22, (17 points) (1) In the “parallelogram rule of verification power” experiment, one end of the rubber strip needs to be fixed on a horizontal board At the other end, the two ends are tied with twine, and the other end of the string has a rope cover (see Figure 1). Two spring balances are required to hook the rope cover and pull the rubber band at an angle to each other. Think this over
