An electric field of intensity 3.50 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 (a) the plane is parallel to the yz -plane, (b) the plane is parallel to the xy -plane, and (c) the plane contains the y -axis and its normal makes an angle of 40.0° with the x -axis.
