Consider a square window of side L=1.00m that lies in the plane of the blackboard at the front of the classroom. Let the outward normal be directed out of the board towards the class. The classroom is immersed in a uniform electric field E= -20.0 N/C i (into the board) and +25.0 N/C j (in the plane of the blackboard and to the right.)
a.) calculate the electric flux through the window.
