[answerhappygod]

a flat capacitor filled with a dielectric material whose
dielectric constant is equal to 80 is connected to a battery to
charge it. The dielectric material is removed from the armatures
while keeping the battery connected. At the end we find that:
A) the energy stored in the capacitor has increased
B) the voltage on the capacitor has decreased.
c) the charge on the capacitor has remained constant.
d) the charge on the capacitor has decreased.
