An electric field of intensity 3.4 kN/C is applied along the x-axis. Calculate the electric flux through a rectangular plane 0.350 m wide and 0.700 m long if the following conditions are true:
(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 45.0° with the x-axis.
