Homework Help: physics need help

Posted by paul on Friday, January 29, 2010 at 2:26pm.

A parallel-plate capacitor made of circular plates of radius 55 cm separated by 0.25 cm is charged to a potential difference of 1000 Volts by a battery. Then a sheet of tantalum pentoxide is pushed between the plates, completely filling the gap between them. How much additional charge flows from the battery to one of the plates when the tantalum pentoxide is inserted?

where do i find the k for tantalum pentoxide?
