Answer:
5.3 nC
Explanation:
The initial charge stored on the capacitor is given by:
(1)
where
is the capacitance of the capacitor
is the potential difference across the capacitor
Substituting numbers into the equation, we have
When the Teflon slab is inserted between the plates, the capacitance of the capacitor is increased as follows:
where k=2.1 is the dielectric constant of the Teflon. Since the voltage V remains constant, this means that the new charge stored by the capacitor (1) will be
and so
