An electric field of intensity 3.7kN/C is applied along the x-axis. Compute the electric flux during 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 35.0° with the x-axis.
