3) For each of the locations indicated below, state what the electric potential is. You do not have to show any work. 20 points total The thin plastic rod at right forms a circle of radius R and has charge +Q uniformly distributed along its length. a) A is at the origin. What is the electric potential at point A? (2 points) The solid metal sphere at right has radius R and charge +Q. b) B is on the surface of the sphere. What is the electric potential at point B? (3 points) c) C is a distance R/2 from the center of the sphere. What is the electric potential at point C? (3 points) d) D is a distance 3R/2 from the center of the sphere. What is the electric potential at point D? (3 points)
BONUS: For parts b-d, if the sphere was plastic instead of metal, and the charge +Q was uniformly distributed throughout the sphere, then would the potential change anywhere? If so would it increase or decrease? (2 points) increase decrease The potential at B would The potential at C would The potential at D would stay the same stay the same increase decrease stay the same increase decrease
