Force on dielectric when inserted in charged capacitor
When we insert dielectric in a charged capacitor then, dielectric is attracted by the capacitor which makes dielectric being "sucked up" by the capacitor. Now, in order to derive the formula for force on dielectric, we apply energy conservation which I feel to be wrong as heat will be lost and hence energy conservation should not be applied, furthermore I feel that the …
