Question

-160 N ? m2/C 0.00 N ? m2/C +160 N ? m2/C -350 N ? m2/C +350 N ? m2/C A nonuniform electric field is directed along the x-axis at all points in space. This magnitude of the field varies with x, but not with respect to y or z. The axis of a cylindrical surface, 0.80 m long and 0.20 m in diameter, is aligned parallel to the x-axis, as shown in the figure. The electric fields E1 and E2, at the ends of the cylindrical surface, have magnitudes of 6000 N/C and 1000 N/C respectively, and are directed as shown. What is the net electric flux passing through the cylindrical surface?

Explanation / Answer

a) -160 N ? m2/C


(-6000+1000)*3.14*0.1^2 = -160 Nm^2/C
