A 25 pF parallel-plate capacitor with an air gap between the plates is connected to a 100 V battery. A Teflon slab (dielectric constant 2.0) is then inserted between the plates, and completely fills the gap.
(a) What is the change in the charge on the positive plate when the Teflon is inserted?

Ответ:
The change in the charge on the positve plate when the Teflon is inserted is +2.5 nC.
Explanation:
It can be showed that the capacitance of a parallel-plate capacitor, can be expresssed as follows:Ответ:
I'm pretty sure it's gas
