Two very large parallel sheets are 5.00 cm apart. Sheet A carries a uniform surface charge density of 9.00 microcoulombs per meter squared, and sheet B, which is to the right of A, carries a uniform charge of 11.6 microcoulombs per meter squared. Assume the sheets are large enough to be treated as infinite.
A) Find the magnitude of the net electric field these sheets produce at a point 4.00 cm to the right of sheet A.
B) Find the magnitude of the net electric field these sheets produce at a point 4.00 cm to the left of sheet A.
C) Find the magnitude of the net electric field these sheets produce at a point 4.00 cm to the right of sheet B.
