这种看法当然不对。主要可以从两个方面谈理由：一是不仅伟大人物有创造力，一般的人也有创造力。可以举出自己知道的事例来证明，如鲁班发明锯子，黄道婆发明纺织法……甚至某幼儿园的小朋友创作一幅画。二是伟大人物也是从一般人开始的，伽利略发现摆的规律时还是一个学生，当时谁也不认为他伟大；发明蒸汽机的瓦特原先只是一个学徒；富尔顿刚发明出来的轮船被人家认为是一个“蠢物”，等等。

星光中学科技小组的小明同学自行设计了一个电子秤，其原理如图2所示，他试图用电压表的示数来反应物体质量的大小．设电源的电压为恒定U，定值电阻的阻值为R₀，滑动变阻器的总电阻为R，总长度为L，滑动触头固定在安放托盘的轻质弹簧上，开始时触头位于变阻器最上端A，并能随轻质弹簧一起自由滑动（接触良好）．已知滑动变阻器的电阻与其接入电路的长度成正比：当在托盘放一质量为m₀的物体时，弹簧的长度会缩短l，若托盘、弹簧的质量以及弹簧的电阻可以忽略不计，请根据上述内容和条件解答如下问题：
