An electric field with a magnitude of 3.50 kN/C is applied along the x axis. Calculate the electric flux through a rectangular plane 0.350 m wide and 0.7 m long assuming that

(a) the plane is parallel to the yz plane;

(b) the plane is parallel to the xy plane;

(c) the plane contains the y axis, and its normal makes an angle of 40.0° with the x axis.
