Unformatted text preview: Phvsics 221Fall2007 Written Homework due Tuesday November 27 1-- A metal sphere of radius 15.0 cm has a net charge of 3.00 x l0-8 C. (a) What is the electric field at the sphere's surface? (b) If V:0 at infinity, what is the elestric potential at the sphere's surface? (c) At what distance from the sphere's surface has the electric potential decreased by 500 V? il-\ "l\trr"1\='\/r, Fot f Z l5,o ,c-\r'^' Slrvc€ y,. t5 + l .
