A particle with a charge of -60.0 nC is located at the center of a non conducting spherical shell of inner radius 18 centimeter and outer radius 38 centimeter. The spherical shell carries charge with a uniform density of -1.87 µC/m3.
(a) Find the electric field strength just barely inside the surface of the non conducting shell?
N/C
(b) Find the total amount of charge on non conducting shell?
C
To answer the next three questions, it is useful to obtain an expression for the electric field strength inside the non conducting shell as a function of distance from the center of the shell.
(c) Find the electric field strength at a distance of 23 centimeter from the center of the shell?
N/C
(d) Find the electric field strength at a distance of 28 centimeter from the center of the shell?
N/C
(e) Find the electric field strength at a distance of 33 centimeter from the center of the shell?
N/C
(f) Find the electric field strength just barely outside the surface of the non conducting shell?
N/C
(g) Assume a proton were to have a circular orbit just outside the spherical shell. Compute the speed of this proton.
