摘要
第4届欧洲物理奥林匹克竞赛实验试题1为隐藏的电荷,本文详细介绍了试题1的命题、虚拟实验考试流程和解答,结合物理背景知识和实际应用介绍了命题目的,并分析了参赛学生的答题情况.试题1通过测量电子的初动能和入射、出射位置,计算出待测电荷的位置和电量,可用于理论力学、原子物理等教学内容.
The 4th European Physics Olympiad experimental exam 1 was about hidden charge.In this paper,the problems,examinations procedures and solutions of experimental question 1 were detailly introduced,as well the motivation of the problem combined with the physics background and practical application was introduced,and finally the situation on the scores of students was analyzed.Using the measured initial kinetic energy and the entry and exit positions of a series of electrons,experimental question 1 could calculate the position and charge of the unknown charge,and then could be applied for teaching theoretical mechanics and atomic physics.
