Solve the following question:
Question: An electric field of magnitude 3.49 kN/C is applied along the x axis.
Part I: Calculate the electric flux through a rectangular plane 0.350 m wide and 0.700 m long in the following cases.
A: the plane is parallel to the yz plane
_________________N • m2/C
B: the plane is parallel to the xy plane
___________________ N • m2/C
C: the plane contains the y axis and its normal makes an angle of 37.8° with the xaxis
__________________N • m2/C
I want you to clarify the physics in this above question.
