摘要:
利用数学软件Maple强大的符号处理功能,根据电势叠加原理计算出了均匀带电圆锥面轴线上任意点的电势,结果表明:圆锥轴线上电势的大小是先增加后逐渐减小到零,并在圆锥内部存在一个电势最高的点;另外,该数学软件在处理较复杂物理问题时简单方便,其图形可视化功能,有利于学生加深对物理问题的理解.
Abstract:
Maple is a mathematical software with powerful symbolic computation. In this paper, based on the principle of superposition of electric potential, the electric potential distribution of a cone carrying a uniform surface charge in the central axis is obtained. The result shows that the electric potential is first increased continuously and then reaches a “peak value”, and then lets up.Maple is particularly useful in physical problems that require extensive calculation. An important feature of Maple is that it can produce instant graphics to serve as a visual guide, which is generally the best way to understand the underlying physics.
