Consider a uniformly charged ring in the XY plane, centered at the origin. The ring has a radius 
and positive charge 
distributed evenly along its circumference.
1. What is the magnitude of the electric field along the positive z-axis?
Use 
in your answer, where 
.
2.The ball will oscillate along the z-axis between 
and 
in simple harmonic motion. What will be the angular frequency 
of these oscillations? Use the approximation 
to simplify your calculation; that is, assume that
