Transcribed Image Text:We have a sphere with diameter (not radius!) d = 6 m and charge density profile Pc (r) = A², A = 6 * 10-8. The change in potential energy of a charge q=5 mC moved from a radius of r=2.3 m inside the sphere to the very edge of the sphere was found to be -25 J. Find the value of the constant w. 4 sig figs
