Find the electric flux (in N·m²/C) through a rectangular area 4.0 cm x 5.0 cm between two charged parallel plates where there is a constant electric field of 29 N/C for the following orientations of the area. (Enter the magnitudes.) (a) parallel to the plates Nm2/C (b) perpendicular to the plates N·m2/C (c) the normal to the area making a 30° angle with the direction of the electric field; note that this angle can also be given as 180° + 30° Nm2/C
