Asquare loop of side l = 5.5 cm is located in the x-y plane with the center of the loop at the origin. the loop carries a uniformly distributed charge q = 79 μc. randomized variables l = 5.5 cm q = 79 μc determine (a)- an expression for linear charge density, λ, in terms of q and l. (b)- find the electric potential, in kilovolts, at the origin due solely to the charge on the bottom side of the loop by integrating the infinitesimal contributions to the potential from the side's infinitesimal segments.
