Concept explainers
The golden earring A disk of radius r is removed from a larger disk of radius R to form an earring (see figure). Assume the earring is a thin plate of uniform density.
a. Find the center of mass of the earring in terms of r and R. (Hint: Place the origin of a
b. Show that the ratio R/r such that the center of mass lies at the point P (on the edge of the inner disk) is the golden mean
