A thin circular ring of radius R has a charge +Q uniformly distributed on the entire loop. O Derive the value of the voltage at a point a distance a

from the center of the ring along the axis that passes through the center of the ring. b) Calculate the electric field created from the ring usingthe potential you found in part (a). You may want to check your final answers to see that in the limit of x >> R, you re-obtain the point charge potential and electric field equations.
