Two effectively infinite and parallel sheets of charge are 6.00 cm apart. Sheet 1 carries a uniform surface charge density of -6.80 μC/m2 while Sheet 2, which is to the right of sheet 1, carries -12.4 μC/m2.
Find the magnitude and direction of the net electric field these sheets produce at a point (a) 2.00 cm to the right of sheet 1; (b) 2.00 cm to the left of sheet 1; (c) 2.00 cm to the right of sheet 2.
