Question

Plane A carries a uniform surface charge density of -8.30 μC/m^2 , and Plane B, which is to the right of A, carries a uniform charge density of +13.6 μC/m^2 . Assume that the planes are large enough to be treated as infinite.The distance between large parallel planes is 5.00 cm.

Part A)  

Find the magnitude of the net electric field these planes produce at a point 4.00 cm to the right of plane A.

Express your answer with the appropriate units. E=?

Part B) Find the direction of this net electric field. Right or left ?

Part C)

Find the magnitude of the net electric field these planes produce at a point 4.00 cm to the left of plane A.

Express your answer with the appropriate units. E=?
