A point charge Q = +24 nC is located at the center of a hollow, conducting spherical shell. The shell has radius R = 12 cm and uniform surface charge density σ. At a distance d = 75 cm from the center of the shell, the electric field is measured to be E 49 kN/C in the radially inward direction. What is o? For the limit check, investigate what happens to σ (and therefore what happens to gin) if the electric field at d becomes extremely weak (i.e., E→ 0). Initial Equations Algebra Work (Symbols only. Don't plug in any numbers yet.) Symbolic Answer: Unit Check Limit Check a) As E 0, what limit does σ approach? b) Why does the result make physical sense? Numerical Answer: (Obtain this by plugging numbers into your symbolic answer.)
