A square that has 12 cm long edges is centered on the x axis in a region where there exists a uniform electric field given by = (3.00 kN/C).
(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 60° angle with the y axis and an angle of 90° with the z axis?
