Unformatted text preview: Massachusetts Institute of Technology Department of Physics 8.022 Spring 2004 Assignment 2: Electric potential Post date: Thursday, February 12th Due date: Thursday, February 19th Be sure to write your name and section number on your pset Please staple multiple pages together 1. Purcell 1.31: Charged soap bubble (10 pts) 2. Purcell 2.4: ~ E and from (10 pts). In addition, identify any surface charge in this distribution (its magnitude and its location). 3. Purcell 2.8: Cylindrical charge distribution (10 pts) 4. Purcell 2.15: Curl and divergence (10 pts). 5. Purcell 2.20: in a gold nucleus (10 pts) 6. Purcell 2.30: at center and corner of a cube (20 pts). Hint: One big cube = eight small cubes. 7. Electric dipole revisited (15 pts): A charge + q is located at z = + b/ 2; a charge- q is located at z =- b/ 2. Find the electric potential at the spherical coordinate ( r,, )....
