hey ,
?
here we go....thanks for the proof....
?
When you remove the dielectric slab then as per the formula
?
C=keA/d the capacitance would decrease and hence the voltage would increase...
Since the charge is constant...Q=CV
?
Try that...!!
?
So in short the charge stays on the plates...(I did this 2 years back..)
Regards :-),

All this thinking is making my head hurt (figure of speech only). I haven't t\
thought this much about 'tonix in ages. I retired last May but it was even
before that when I last brain stormed about it.

OK, here's an experiment. Take a conductor and charge it. I can do charge
some dielectric materials, but not conductors. The if the charge is really
on the plates it would be there when the dielectric is removed. Now if
you mean that you can measure the potential of the charge at the plates,
I can buy that.
