Unformatted text preview: Phys 212 - Fall 2009 8/31/2009 Electric Field III Reminders HW2 Due Wednesday 1 st Test - Wed. Sept 16 Field Lines Which of the following statements concerning electric eld lines is false ? a) Electric eld lines between two charged particles are often curved. b) Electric eld lines are a method proposed by Michael Faraday to map the electric eld at various locations. c) Electric eld lines can be used to indicate the local magnitude of the electric eld. d) Electric eld lines are always directed radially away from a positively-charged particle. e) An electric eld line indicates the direction of the force on an electron placed on the line. Review - Field Lines 1. Field lines point away from positive charges. 2. Field lines point toward negative charges. 3. Field lines ll space continuously. 4. Direction of a straight eld line or the tangent to a curved line gives the direction of E . 5. Density of lines/area gives the magnitude of E . 6. Field lines never cross. Field Lines for Charged Objects Use symmetry of the charge distribution to predict eld direction....
