a) An electric field of magnitude 4960 N/C is applied along the x axis. Calculate the electric flux through a rectangular plane 0.455 m wide and 0.46 m long if the plane is parallel to the yz plane. Answer in units of N·m2/C.
b) Calculate the electric flux through the same rectangle if it is parallel to the xy plane.
c) Calculate the electric flux through the same rectangle if it now contains the y axis and its normal makes an angle of 60? with the x axis.
