Two isolated uniform spheres of masses m_1 and m_2and radii 2R and R respectively are released from rest from the given position. Find the distance from m_1where they meet. (Position of centre of mass does not change as gravitational force acting between them is an internal force)

1.	Two isolated uniform spheres of masses m_1 and m_2and radii 2R and R respectively are released from rest from the given position. Find the distance from m_1where they meet. (Position of centre of mass does not change as gravitational force acting between them is an internal force)
Answer» SOLUTION :`((m_2)/(m_1+m_2))3R`
