Abstract

The fundamental dynamic properties of the planar electric charged particle are investigated experimentally. The experiment is conducted using electric charged spheres(4 table tennis balls with conductive surfaces) suspended by insulating strings to cancel the gravitational force. The measurements of the equilibrium angles and the natural frequencies of oscillation agree well with the analytical predictions with some error, respectively.

본 논문에서는 평면 계에서의 전기전하 입자의 기본적인 동특성을 간단한 모델을 이용하여 실험적으로 살펴보았다. 실험에서는 전기전하입자 모델로 4개의 소형구(전도체로 표면을 잘 도포한 탁구공)를 사용하였으며, 측정시 중력효과를 배제하기 위하여 잘 절연된 줄에 매달린 형태를 적용하였다. 실험으로 측정한 평형위치(각도)와 전하입자의 고유동수는 계산된 값과 상당히 근접함을 보인다.
