The electric field through a region of space is given by:
E = (-1.10×10^4 N/Cm2)xyi + (-6.20×10^4 N/Cm)xj + (-6.60×10^4 N/Cm)yk
A square is located in the x-y plane, at z = 0, as shown in the figure below. The sides of the square have length 7.86 cm. What is the electric flux through the square?
Flux = E * dA
The Attempt at a Solution
The square is in the x-y plane, so we can ignore i and j components of the electric field. The thing that is throwing me off is the y in the k component of the electric field. This is what I tried:
But it gives me an incorrect answer. Help?
