Two lead balls of masses `m` and `5m` having radii `R` and `2R` are separated by `12R`. If they attract each other by gravitational force, the distance covered by small sphere before they touch each other is

Two spherical bodies of masses m and 5m and radii R and 2R respectively, are released in free space with initial separation between their centres equal to 12 R. If they attract each other due to gravitational force only, the distance covered by smaller sphere just before collision is

Two spherical bodies of masses m and 5m and radii R and 2R respectively, are released in free space with initial separation between their centres equal to 12 R. If they attract each other due to gravitational force only, the distance covered by smaller sphere just before collision is

Two spherical bodies of masses m and 5 m and radii R and 2R respectively are released in free space with initial separation between their centres equal to 12R. If they attract each other due to gravitational force only then find the distance covered by smaller sphere just before collision

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

Two spherical bodies of masses m and 6m and radii R and 2R respectively are released in free space with initial separation between their centres equal to 10 R . If they attract each other due to gravitational force only , then the distance covered by smaller sphere just before collisions will be

Two spherical bodies of masses m and 4 m and radii R and 2R respectively are released in free space with initial separation between their centres equal to 15 R. If they attract each other due to gravitational force only, then the distance covered by smaller sphere just before collision will be
