An electric field with a magnitude of 2.20 𝑘𝑁/𝐶 is applied along the x-axis. Calculate the
electric flux through a rectangular plane 0.77 m wide and 1.44 m long assuming that (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 26.7° with the x axis.
