An electric field of intensity 2.5 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.
