For Gauss' law where is the Electric field evaluated? O All points in space The center of the charge distribution At an arbitrary point in space On the Gaussian surface o It depends on the symmetry An arbitrarily shaped uncharged conductor is added to a field map. Which field lines are affected by the addition of the conductor? No field lines are affected Only field lines that intersect the conductor are affected Most field lines are somewhat affected
An electric field can be created by a single charge or a distribution of charges. The electric field a distance from a point charge has magnitude E = k|q'|/r^2. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge is placed in an electric field created by q',...
The potential in a region of space due to a charge distribution is given by the expression V = ax2z + bxy − cz2 where a = −9.00 V/m3, b = 2.00 V/m2, and c = 8.00 V/m2.

2. Dipole-dipole force The charge distribution where two equal but opposite charges are separated by a fixed distance δ is called a dipole and is very common and important in nature Consider two dipoles, each consisting of charges tq separated by a distance 6. The axes of two dipoles are parallel and their midpoints are separated by a distance r. One is inverted compared to the other. See the figure....
6. (10 points Extra Credit) Electrodynamics is not the only subject that utilizes Gauss' Law. We can also use it to study Newtonian gravity. The acceleration due to gravity (9can be written as, where G is Newton's gravitational constant and ρ is the m ass density. This leads us to the usual formulation of Newton's universal law of gravity,或刃--GM(f/r, as expected (if we assume V xğ-0). This "irrotational" condition allows us write (in analogy to the electric field), --Vo and...
