368(3): Expressions for Z(r)

This note shows via Eq. (11) that Z as a function of r is an inverse square law and always negative. So in order to lift the point of the gyro another force is needed in the positive Z(r) direction as discussed already. The motions of theta and phi are defined by Eqs. (16) and (17) respectively. There is plenty of scope here for interesting graphics similar to UFT270.
