Coulomb's law quantitative exploration vacuum experiment device

Abstract

The invention discloses a Coulomb's law quantitative exploration vacuum experiment device which comprises a mounting base, and a vacuum experiment device and a clamping mechanism are arranged on the mounting base. According to the invention, the charged charges can be ensured to be in a vacuum state in the glass tube, the influence of other media on the charged charges can be effectively solved through the plastic film attached in the glass tube, and the accuracy of the experiment is ensured; a clamping mechanism is arranged at the end part of the glass tube, so that multiple groups of inclination angles of the glass tube can be stably adjusted, and the electrostatic force between corresponding charges can be calculated; the distance between the two charges can be directly read through the scales on the outer wall of the glass tube; the electric quantity of charges in the glass tube can be conveniently changed through the conductive needle. The coulomb's law experiment device can effectively perform quantitative exploration on the coulomb's law, solves the problem that students understand the coulomb's law in a one-sided and non-deep manner in a traditional experiment device, can provide experiment operation experience for the students, and cultivates the scientific exploration ability of the students.

Description

Technical field [0001] The present invention belongs to the technical field of teaching teaching, and in particular, in particular, the quantitative exploration of a quantitative exploration of coulomb law. Background technique [0002] The square anti-ratio relationship between static power interactions is the experimental measurement of the French military engineer Kulomb (C · A Coulomb, 1736 ~ 1806). In 1785, Coulomb used its own knowledge about torsion, and designed a precision twisher and experiment with the measurement of electric power. In such an experiment, Coulomb depends on the conclusions of the repulsive force between the two balls of the same class, the square of the distance between the two balls. However, limited to factors such as historical stages, science and technology levels, the accuracy of this experiment is not very high, and the relationship between the gravity and distance between the heterogeneous charge can be unable to explore the relationship between...

AI Technical Summary

Problems solved by technology

Limited to the accuracy of the instrument and problems in operation, quantitative experiments are generally not demonstrated, and this cannot cultivate students' inquiry ability, and lack of experience in operation, and at the same time will cause students to have a one-sided and not deep understanding of Coulomb's law
