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
1)
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.

Problem 6.74 4 of 9 Constants Periodic Table Part A A uniform sphere has mass M, and radius r. A spherical cavity (no mass) of radius r/2 is then carved within this sphere as shown in the figure(Figure 1)(the cavity's surface passes through the sphere's center and just touches the sphere's outer surface). The centers of the original sphere and the cavity lie on a straight line, which defines the 3 axis. With what gravitational...
