Abstract

The purpose of this research was to study the behavior of the motion of electrically charged particles moving in a central force function of radius. The study began by building a model of central force function of radius. Then, Lagrangian mechanics was used to calculate the distance of motion charged particles and effective potential using the central force function of radius. The results are being plotted on a graph by using a computer program where impact of the electric changed particles and variable changes can be analyzed and interpreted.
