A thin disk with a circular hole at its center, called an
annulus, has inner radius R1 and outer radius R2. The disk has a
uniform positive surface charge density σ on its surface. (Figure

A)The annulus lies in the yz-plane, with its center at
the origin. For an arbitrary point on the x-axis (the axis
of the annulus), find the magnitude of the electric field E⃗ .
Consider points above the annulus in the figure.
