About behavior of electrostatic pendulum near conducting or dielectric plate
Interaction of a charged ball with conducting or dielectric plates is examined. Two simultaneous stable equilibria of the electrostatic pendulum are detected. The proposed theory satisfactorily agrees with the experimental data. Numerical simulation showed possibility of chaotic oscillations of the pendulum.

Accurate Experimental Method For Measuring Electronic Number Based On Force Balance Theory
A simple physics experiment method for measuring number of micro power electronics is designed in this paper. Based on simple mechanical balance theory and optical reflection theory, the method accurately transforms the measurement of electronic number into the length measurement and deduces the formula for measuring micro-power.

Image-charge effects on an electrostatic pendulum in mechanical equilibrium
A charged pendulum suspended in mechanical equilibrium by an insulated string and deflected by a uniform electric field was investigated theoretically and experimentally. When the uniform electric field is generated by a pair of large parallel conducting plates, there is an additional force of attraction between the pendulum and its corresponding image charges, which can dramatically affect the pendulum's equilibrium deflection.
