Why is a dielectric slab repelled when inserted between the plates of a parallel plate capacitor which is connected to a battery of constant emf?
I think that it should get repelled as when the dielectric is inserted in the capacitor (connected to a battery) it increases the potential energy . And in most simple terms , the system tries to decrease its energy by repelling it . But I don't know if it is correct . And if it is correct please can you elaborate how it actually happens.
