Question
001 (part 1 of 3) 10.0pointsAn electric field of magnitude 3210 N/C is
applied along the x axis.
Calculate the electric flux through a rect-
angular plane 0.208 m wide and 0.39 m long
if the plane is parallel to the yz plane.
Answer in units of 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.
003 (part 3 of 3) 10.0 points
Calculate the electric flux through the same
rectangle, but now the rectangle contains the
y axis and its normal makes an angle of 25 ?
with the x axis.
Answer in units of N · m2/C. 001 (part 1 of 3) 10.0points

Explanation / Answer
E = 3210 N/C, a = 0.208 m, b = 0.39 m 001) E*a*b*cos(0) = 260 Nm2/C 002) E*a*b*cos(90) = 0 003) E*a*b*cos(90 - 25.7) = 26.7 Nm2/C
