Question
When a dielectric slab is gradually inserted between the plates of an isolated parallel-plate capacitor, the energy of the system decreases. What can you conclude about the force on the slab exerted by the electric field?
$\text{F}=-\frac{\delta\text{U}}{\delta\text{x}}$
So, as the energy decreases, the force due to the electric field of the capacitor increases when the dielectric is dragged into the capacitor.Generate a complete, print-ready paper with questions like this in minutes — across 16+ boards, with answer keys.
