Electric flux thru cube
December-10-12
4:26 PM
A cube has sides of length L and sits on the coordinate
axes. The electric field in the region is E=(a+bx)i+cj.
Find the electric flux through each of the six cube faces
and the total electric flux.

10:39 AM
A nonuniform electric field is given by the expression
E=ayi+bzj+cxk where a, b, and c are constants. Determine
the electric flux through a rectangular surface in the xy
plane, extending from x=0 to x=w and from y=0 to y=h.

5:33 AM
Use Gauss's Law to find the electric field due to a) a point
charge, b) an infinite line of charge and c) an infinite sheet of
charge. The working form of Gauss's Law is E=Q in/Aεo where
Qin is the charge inside the Gaussian surface and A is the
surface area of the Gaussian surface through which the
electric field is parallel to the area vector.
