1. The problem statement, all variables and given/known data The electrons of the uranium atom can be approximated as a uniform density sphere with radius 7.4 x 10-13 cm. The nucleus is a point at the center with a charge of +92e, and there are 92 electrons. a. Calculate the electric potential and electric field at the surface taking only the electrons into account. b. Calculate the electric potential and electric field at the surface taking only the nucleus into account. c. Compare the 2 sets of values. d. A more classical picture has the electrons in planetary orbits. At any instant, there are 92 electrons arrayed uniformly about the sphere. Discuss how this changes the answers to the 3 previous parts. 2. Relevant equations 3. The attempt at a solution I am not entirely understanding the setup for this problem. I am having a hard time understanding what is being described. If I am understanding it correctly, I would guess I would have to use Gauss Law to get the value for E, and then use that value to find V. Can anyone comment on my thought process?
