Two very large, nonconducting plastic sheets, each 10.0 cm thick, carry uniform charge densities σ 1 , σ 2 , σ 3 and σ 4 on their surfaces, as shown in the following figure(Figure 1). These surface charge densities have the values σ 1 = -7.70 μC/ m^2 , σ 2 =5.00μC/ m^2 , σ 3 = 2.70 μC/ m^2 , and σ 4 =4.00μC/ m^2 . Use Gauss's law to find the magnitude and direction of the electric field at the following points, far from the edges of these sheets.
Part A What is the magnitude of the electric field at point A , 5.00 cm from the left face of the left-hand sheet? Express your answer to three significant figures and include the appropriate units.
Part B What is the direction of the electric field at point A , 5.00 cm from the left face of the left-hand sheet?
Part C What is the magnitude of the electric field at point B , 1.25 cm from the inner surface of the right-hand sheet? Express your answer to three significant figures and include the appropriate units.
Part D What is the direction of the electric field at point B, 1.25 cm from the inner surface of the right-hand sheet?
Part E
What is the magnitude of the electric field at point C, in the middle of the right-hand sheet?
Express your answer to three significant figures and include the appropriate units.
Part F
