## Main Question or Discussion Point

hi

in what direction does the electrostatic force act when we insert a dielectric within a capacitor? and when we remove the dielectric? supposedly they act in opposite directions in each case, and either push or pull the dielectric out or into the capacitor. i m not able to understand how the direction is acting perpendicular to the direction in which the charges are. for example, q is the charge on one plate.put a dielectric in and charge on dielectric is -q', where q' is less than q.then force is given by coulombs law, and let it be f. now that f is pulling the dielectric towards the plate no? (attractive force). so where does the force where that pushes or pulls the dielectric out or in come from?

thanks
