Homework Statement
A 4.00 kg block carrying a charge Q=50.0 µC is connected to a spring for which k=100N/m (see diagram). The block lies on a frictionless horizontal track, and the system is immersed in a uniform electric field of magnitude E = 5.00x10^5 V/m, directed as shown. If the block...

[b]1. A closed surface with dimensions a = b = 0.400 m and c = 0.600 m is located as shown in the figure (be aware that the distance “a” in the figure indicates that the rectangular box sits a distance “at” from the y-z plane). The electric field throughout the region is nonuniform and given...
Homework Statement
A point charge Q is located on the axis of a disk of radius R at a distance b from the plane of the disk (Fig. below left). Show that if one fourth of the electric flux from the charge passes through the disk, then R = sqrt(3)b.
