Test Preparation on Rotational Motion-I-Physics Test Series For NEET 2020

Two spherical bodies of mass M and 5M 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 the distance
covered by the smaller body just before collision is

The distance between the carbon atom and the oxygen
atom in a carbon monoxide molecule is 1.1 Å. Given, mass
of carbon atom is 12 a.m.u. and mass of oxygen atom is 16
a.m.u., calculate the position of the center of mass of the
carbon monoxide molecule
