MIT NOTES ASK TOUR TEACHER PRACTICE ANOTHER A uniformly charged spherical shell has inner and outer radii of 29.0 cm and 32.0 cm, respectively. A point charge of -45.0 nC is located at the center of the spherical shell. A proton orbits around this arrangement just outside the spherical shell with a speed of 8.29 x 105 m/s. What is the volume charge density of the spherical shell? (Include the sign of the value in your answer. Enter a number. oplies the needed centripetal force that keeps the proton in a circular orbit? How is the net charge related to the charge on the spherical shell? µC/m³

A point charge of charge +Q is at the center of a spherical shell of charge with charge -3Q. The shell has radius R. Find the magnitude and direction (toward the center or away from the center) of the electric field at a distance rR from the point charge in terms or Q, r, R, and any constants (i.e. k-). (Hint: Youcan either use Gauss' Law or superposition for this!) -30 R

The tolerance of the answer is +-1 on the 3rd significant digit.
