Hey SIr , (Addressed to Sir J D Grififfiths)
Last year when I took basic electricity and magnetism course , my instructor discussed some interesting ideas which you discussed in your book ''Introduction to Electrodynamics'' ,one of that was calculating force exerted on a dielectric while it's to be inserted in a parallel capacitor(Chapter 4 Electric Fields in matter;page 196-7)
Therein you have made one mistake ! -So said my instructor !
You said -
Reference-
Clarification-
When the capacitor isn't connected to a battery V will change , so the force on dielectric (exerted by capacitor pates) in case when the capacitor plates are maintained at constant potential difference, will differ from the force exerted when the capacitor plates aren't maintained at constant potential difference.
One more thing
When we connect a capacitor to a battery directly , half of the work done by battery is stored in capacitor in form of electrostatic potential energy (and the other half is radiated out in form of electromagnetic radiations)
So,
as of the example of inserting dielectric in parallel plate capacitor , will there be any play of the phenomenon of energy being radiated out in form of electromagnetic radiations (as in the case I mentioned above) ?
Thank you for reading Sir
I am waiting for your reply
Yours enthusiastic student !
