Question

An electric field of magnitude 3640 N/C is
applied along the x axis.
Calculate the electric flux through a rectangular
plane 0.166 m wide and 0.72 m long
if the plane is parallel to the yz plane.
Answer in units of N · m2
/C.
435.05 N. m2/C
002 (part 2 of 3) 10.0 points
Calculate the electric flux through the same
rectangle if it is parallel to the xy plane.
Answer in units of N · m2
/C.

i got my first answer correct but i could not do the second part can you help me please

Answer 1

E dot A = 3640 * .166 * .72

= yes, 435 N m^2 /C

If the plane is turned 90 degrees, none of the E field goes through it. E dot A = 0 The answer is ZERO
