(c17p74) A parallel-plate capacitor made of half-circular plates
of radius 20 cm separated by 2.00 mm is charged to a potential
difference of 800 volts by a battery. Then a sheet of polyethylene
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 polyethylene is inserted?
Dielectric constant for some materials:
mylar: 3.1
polyethylene: 2.6
polyvinyldifluoride: 11.
tantalum pentoxide: 25.
Teflon: 2.1
