Each figure shows a rectangular box with dimensions L x W x H, placed in various electric fields of uniform magnitude Eo For each case, find an expression for the net electric flux e out of the box in terms of E., L, W, and H. The field in each case is assumed to be perpendicular to the side faces of the box. DE = DE =

During an experiment, a certain device produces a constant, uniform electric field of (33.7 N/C) i + (64.5 N/C) i Nearby, a student holds a large circular hoop with a diameter of 1.25 m such that the hoop is parallel to the x-z plane. What is the electric flux through the hoop? electric flux: (N-m)/C Another student bumps the field-producing device so that the electric field is now (26.9 N/C) î + (16.7 N/C) Â What is the new electric flux through the hoop? electric flux: (N-m2)/C

A thin, metallic spherical shell of radius 0.247 m has a total charge of 8.53 x 10-6 C placed on it. A point charge of 4.15 x 10-6 C is placed at the center of the shell. What is the electric field magnitude E a distance 0.745 m from the center of the spherical shell? E = Does the electric field point outward from the center of the sphere or inward? O outward inward
