Question

Two very large parallel sheets are 5.00 apart. Sheet carries a uniform surface charge density of -8.30 , and sheet , which is to the right of , carries a uniform charge of -11.5 . Assume the sheets are large enough to be treated as infinite.
Find the magnitude of the net electric field these sheets produce at a point 4.00 to the right of sheet A.
Find the direction of the net electric field these sheets produce at a point 4.00 to the right of sheet A.
Find the magnitude of the net electric field these sheets produce at a point 4.00 to the left of sheet A.
Find the direction of the net electric field these sheets produce at a point 4.00 to the left of sheet A.
Find the magnitude of the net electric field these sheets produce at a point 4.00 to the right of sheet B.
Find the direction of the net electric field these sheets produce at a point 4.00 to the right of sheet B.







Explanation / Answer

a)

E_net = E_A - E_B
charge = /
E_A = -8.9 * 10^-6 C/m^2 / (8.85*10^-12 F/m) = -1.006*10^6 N/C
E_B = -12.8 * 10^-6 C/m^2 / (8.85*10^-12 F/m) = -1.45*10^6 N/C
E_net = 4.44 * 10^5 N/C
b)
E_net = -(E_A + E_B)

E_net = 2.46 * 10^6 N/C
c)
E_net = E_A + E_B

= -2.46 * 10^6 N/C
