Thanks or your reply it's a really good start. But I'm trying to find someway which is 'adjustable' and 'controllable' ...

Hello I need some advice about electrostatic levitation concept and am trying to make an experimental setup for that. Consider two parallel plates with the same sign charge and the bottom plate is fixed in place. Therefore there will be a repulsive force which pushes the upper plate...

Well in this case I know that electric field around each point charge is calculated as: kQ/(r2) (undefined at the position of point charge) and the force is defined as F=q.E which results in kQq/(r2). I believe I can use the same approach for attracting parallel plates: Total net field between...

Thanks for your prompt response. So what I understand from your suggestion is that I can have a first order estimation of repulsive force by calculating available charges on each plate (Q1 = Q2) and use Coulomb's law as k.Q1.Q2/(d^2), is that right? But I'm a little confused here since I have...

Hi I was thinking about two parallel plates with same charges (there's no electrical field between them). How can we calculate the repulsive force? Does anyone have any ideas besides numerical integration? Thanks

Thanks Greg. Hope I can both learn and dedicate in here :)

Hello This is Arjang and I'm a PhD student in mechanical engineering at UT Austin. I'm working on a multidisciplinary research which involves electrostatics, heat transfer and fluid mechanics. I'm developing new techniques to enhance heat transfer using electrostatic forces and I'm looking...
