Physics

A circular ring of radius R with a total charge 2Q uniformlydistributed along its circumference lies in the x y plane with itscenter at the origin.

(a) Find the electric field at a point with coordinates (0, 0,z0). Show all steps in your calculation. Don’t forget to representthe field in vector form - magnitude and direction!

(b) Find the locations along the z axis where the electric fieldhas its largest values (don’t forget that because of the symmetryof the situation, there are two points where the field has it’slargest magnitude).
