A square that has 16 cm long edges is centered on the x axis in a region where there exists a uniform electric field given by E→ = (2.00 kN/C)i^.
(a) What is the electric flux of this electric field through the surface of a square if the normal to the surface is in the +x direction?
(b) What is the electric flux through the same square surface if the normal to the surface makes a 50o angle with the y axis and an angle of 90o with the z axis?
