A particle P of mass m can slide along a smooth rigid straight wire. The wire has one of its points fixed at the origin O, and is made to rotate in a plane through O with constant angular speed . Show that r, the distance of P from O, satisfies the equation

r^·· - π²r = 0.

Initially, P is at rest (relative to the wire) at a distance a from O. Find r as a function of t in the subsequent motion.
