a) What is the charge before the Teflon is removed? Q= C
b) What is the potential difference before the Teflon is removed? V= V
c) What is the electric field before the Teflon is removed? E= V/m
d) What is the charge after the Teflon is removed? Q= C
e) What is the potential difference after the Teflon is removed? V= V
f) What are the electric field after the Teflon is removed?

    a) What is the charge before the Teflon is removed? Q= C

    NO
    Q = C V
    same in part d

    The field E is 9 Volts/(10^-4 mters)
    with or without teflon
    However C depends on the material
