When the styrofoam is suspended, the gravitational force is balanced by the Electric field produced by the sheet below, Hence we can write,
The electric field produced by the sheet is given by,
Substituting values we get,

Two very large parallel sheets are 5.00 cm apart. Sheet A
carries a uniform surface charge density of -6.80 μC/m2 , and sheet
B, which is to the right of A, carries a uniform charge density of
+12.1 μC/m2 . Assume that the sheets are large enough to be treated
as infinite.
PART C:
Part E:
