Suppose we connect a block of conducting material that has a net negative charge to two wires and a small light bulb as shown below. The wire to the left of the conducting material is now brought into contact with the conducting material. Will there be any movement when this final connection is made? If yes, which way and for how long? If no, why not? EXPLAIN! In a second situation, we replace the conducting material with a block of...

(6.) An infinite line of charge is parallel to the plane of an infinite sheet of charge. If the line of charge is a distance b above the sheet, what is the relationship between the densities , o and the distance b that will allow the net field created by the distributions to be zero at some point between the two?

(a) We have said that Gauss’s law is always true, but only useful for calculating the electric field created by source charge distributions that are spheres, infinite straight cylinders, and infinite flat sheets, and even those cases have additional restrictions. Explain why we are limited to those distributions. Discuss what additional restrictions apply. For example, can we use Gauss’s law to find the field of a sphere whose density depends on distance r from the center? Can we do it...

5. A charged rod is touched to a neutral object. When the rod is removed, the object is found to have acquired a charge of +1 C (this is actually an extremely large charge). Is the object heavier or lighter than when it was neutral? How much is the difference in the object's mass before and after the object is charged? 6. A large and equal charge is deposited on the left end of two rods, one metallie (conductor) and...

Two small negatively charged spheres spaced 35.00 cm apart have equal amounts of net charge. If the magnitude of the force of repulsion between them is 2.430 x 1021 N, How many excess electrons must be present on each sphere? (For this calculation, use ke-8.988 x 109 Nm2/C2 for Coulomb's constant and use qo 1.602 x 10-19C for the charge of an electron).

A very large sheet of insulating material has had an excess of electrons placed on it to yield a surface charge density of -4.00 nC/m2. (a) As the distance from the sheet increases, does the potential increase or decrease? (e) increase O decrease Can you explain why without any calculations? The electric field points in the direction of increasing potential while pointing away from negative...

#8 Storm clouds may build up large negative charges near their bottom edges. The earth is a good conductor, so the charge on the clouds attract an equal and oppositeLT charge on the earth under the cloud. The electric field strength near the earth depends on the shape of the earth's surface, as we can explain with a simple model. The top metal plate in the figure has a uniformly distributed negative charge. The bottom metal plate, which has a...
