Question

both parts pls

Review Part B An early model of the atom, proposed by Rutherford after his discovery of the atomic nucleus, had a positive point charge +Ze (the nucleus) at the center of a sphere of radius R with uniformly distributed negative charge -Ze. Z is the atomic number, the number of protons in the nucleus and the number of electrons in the negative sphere. What is E at the surface of the atom? Give your answer as a multiple of e/ep- Express your answer in terms of some or all of the variables R, Z, e, E0, and . Submit Part C A uranium atom has Z 92 and R0.10 nm What is the electric field strength at Express your answer with the appropriate units. - | Value Units Submit Request Answer

Answer 1

B)

Electric field, E = 0

C)

Electric field, E = ((92 x 1.6 x 10^-19)/(4 pi x 8.85 x 10^-12)) [(1/(0.5R)^2) - 0.5R/R^2]

Substituting the value of R, we get

Electric field, E = 4.64 x 10^13 N/C
