Two spherical bodies of mass M and 5 M and radii R and 2R respectively are released in free space with initial separation between their centers equal to 12 R. If they affact each other due to gravitational force only, then the distance covered by the smaller body just before collision is

A collision is an event where two or more bodies come into contact and exert forces on each other, causing momentum and energy changes. Class 11 Physics Gravitation CBSE EXAM 2024-25
