Please help. Thank you.
(3.) (40 pts) An insulating sphere of radius a has an embedded nonuniform charge den- sity: p(P) = (1+) where pe is a positive constant (this charge density is only valid for r <a). Sur- rounding the sphere, and concentric with it, is a conducting shell of inner radius b> a and outer radius c which is charged (not neutral). I do not know what the charge on the conductor is, but I am told that...

tried to solve this exercise:
Which says to think about the Hall effect, but usually there’s
an external current flow when considering this effect, so I tried
to solve the exercise in another way. My questions are:
1) did I solve it right (see below)?
2) how can I solve the exercise considering the Hall effect
(and Lorentz force) ?

Thanks!
5. (10 pts) (a) Einstein's explanation of the photoelectric effect launched the study of quantum mechanics. A minimum frequency of UV light shining on a metal is necessary to create a current. Explain in your own words, how Einstein explained this particular observation. Be to the point. Points will be deducted for answers that do not have enough detail, or if there is irrelevant information. (b) You discover a new metal. You conduct a photoelectric experiment on the metal...

? A total charge, Q, is distributed uniformly throughout a cube of edge length, a. Is the resultant Q electric field at an external point, P, a distance r from the center. C, of the cube, given by E 4160 m2 If not, can E be found by constructing a "cocentric" cubical Gaussian surface? If not, explain why not. Can you say anything about E ifr » a?

Sorry this problem has so many
parts--thank you in advance for your effort.
Conservative Forces It takes work to lift an object under the influence of the Earth's gravitational force. This increases the gravitational potential energy of the object. Lowering the ob- ject releases the gravitational potential energy that was stored when it was lifted. When you studied the gravitational force, you applied the term conservative to it because it allows the recovery of all of the stored energy. You...
