A ring of radius R=4 m has mass of m1=5.4×109 kg, which is distributed uniformly over its circumference. A highly dense particle of mass m2=5.4×109 kg is placed along the axis of the ring at a distance x0=3 m from the centre. Neglecting all other forces, except mutual gravitational interaction between the ring and particle. Calculate displacement of the ring when particle is at the centre of the ring. |
