Question

How to determine if the situation is electrostatic or not? I need help with all the sections in each of the 3 questions. But I'm having trouble understanding the material and need some guidance.

(30 points total) "Electrostatics" requires that the electric fields produced by any moving "test charges" be small compared to the main field produced by the static charges. A static field is established by applying a potential difference of 3.65 × 104 V between two large parallel plates set 4.35 cm apart. A small particle carrying a charge of 2.76 × 10-7 C moves into the region between the plates. Your concern is with whether this charge is sufficiently "small" that the system can still be treated as "electrostatic"? Explain how you will determine whether this can be treated as an electrostatic situation. What standards will you use? What calculations will you have to make? (12 points) Perform the calculations, and explain why the system should or should not be considered electrostatic. (12 points) Draw the field lines between the plates, taking the test charge into account. Make the drawing as realistic as possible, so that you can see whether the supposedly uniform field is seriously bent out of shape. (6 points) points)explain c. (24 points total) The earth has a magnetic field of about 0.5 G. The B field points outward at the south pole and inward at the north pole, meaning that the earth's geographical north pole is (close to) a magnetic south pole. It is believed that the magnetic field originates from currents in earth's molten outer core, which extends from a radius of 2500 km to 3400 km from the center of the earth. a. Using a very crude model, represent this current as a thin circle at a distance of 3000 km from the center of the earth and cen such a current that would be necessary to produce a field of 0.5 G at the earth's north pole. (The earth can simply be considered to be a sphere Go to the Web or other sources, and try to find a more adequate model for the earth's magnetic field. Provide enough detail to show you understand it. As always, list any sources you use How would it differ from the simplified model? Can it explain effects for which the simplified model cannot account? (12 points) tered on the earth's axis. Find the magnitude and direction of with a radius of 6380 km.) (12 points) b. 3. (36 points total) A continuous beam of electrons is emitted from a particle accelerator in a horizontal direction. The number density of the electrons is 8.32 × 1015 m-3, they are moving at a speed of 2.55 × 106 m/s and the beam has a radius of 3.85 mm Find the current carried by this electron stream. (Hint: first find the current density from number density of the electrons.) (12 points) Find the magnitude and direction of the magnetic field produced by this stream at a point on the"surface" of this beam. (12 points) It is desired to bend this beam into a circle of radius 3.2 m. How large an external magnetic field would be needed to accomplish this? (12 points) b.
