a Ex06 point 0 We consider on are of circle O, and radius R, seen from 0 under angle 2d. Thus are is loaded with positive and constant linear density A a) Determine the electrostatic fueld at pount O. b) Deduce the electrostatic field created at uniformly charged corde. 07 same questions for the electrostatic potential. We note that the potential is zero at infunuty. What force would a positive Sharge q' exert on the are?. by a A t +-Om + - da B 3.
