electrostatic Force Calculation

Please login with a confirmed email address before reporting spam

Dear Friends, I really need to know how to calculate electrostatic force on the plates of a capacitor. While I am moving the plates closer, the electrostatic force changes but the force on any point between plates is also identical while the force should be inversly proportional to square of the distance. The way I am calcuation the Electrostatic force is as follow, please let me know if this steps are correct and why the force on all the points are identical.

2D plot group>Arrow surface>Expression>Electrostatic>MEchanical>es.forcex_0,es-forcey-0.electromagnetic force(spatial frame)

Thank you, Mehdi.
