When two blocks connected by a spring move towards each other under mutual interaction

Two objects of masses m and 4m are at rest at an infinite separation. They move towards each other under mutual gravitational attraction. If G is the universal gravitaitonal constant, then at separation r

Two objectes of mass m and 4m are at rest at and infinite seperation. They move towards each other under mutual gravitational attraction. If G is the universal gravitational constant. Then at seperation r

Two particles of masses 2 kg and 3 kg are at rest separated by 10 m. If they move towards each other under mutual force of attraction, the position of the point where they meet is
