Here is an easy one:
Say there is a very long piece of string (131,479,658 feet) that is wrapped exactly around the Earth's equator and a much shorter piece of string (5.2 inches) that is wrapped exactly around a golf ball. Assume both the earth and the golf ball are perfect shperes; the strings are both equidistant from the center of their respective spheres at all points.
If we increase the length of either string, it must now be lifted off the surface of the earth of golf ball to be equidistant from the center at all points. Say we add 1 foot of length to each string. The string around the earth is now 131,479,659 feet (+0.0000008%) and the string around the golf ball is now 17.2 inches (+230.8%).
Which longer string (the one around the earth or the one around the golf ball) must be lifted higher off the surface to maintain a perfect circle that is equidistant from the center of the sphere at all points?
