Find an expression for the position y (along the positive axis perpendicular to the ring and passing through its center) where the electric field due to a charged ring is a maximum. Also find an expression for the electric field at that point. (Use the following as necessary: R for the radius of the ring, Q for the charge on the ring and k for Coulomb's constant. Enter the magnitudes. Assume Q is positive.) y = E =
