Two spherical bodies of mass M and $\displaystyle 5$ M and radii R and $\displaystyle 2$ R are released in free space with initial separation between their centres equal to $\displaystyle 12$ R. If they attract each other due to gravitational force only, then the distance covered by the smaller body before collision is :
Official answer
(3)
7.$\displaystyle 5$ R
