A body $$A$$ of mass $$M$$ while falling vertically downloads under gravity breaks into two-parts; a body $$B$$ of mass $${1 \over 3}$$ $$M$$ and a body $$C$$ of mass $${2 \over 3}$$ $$M.$$ The center of mass of bodies $$B$$ and $$C$$ taken together shifts compared to that of bodies $$B$$ and $$C$$ taken together shifts compared to that of body $$A$$ towards

does not shift

depends on height of breaking

Consider the following two statements :

$$A.$$ Linear momentum of a system of particles is zero

$$B.$$ Kinetic energy of a system of particles is zero.

then

$$A$$ does not imply $$B$$ and $$B$$ does not imply $$A$$

$$A$$ implies $$B$$ but $$B$$ does not imply $$A$$

$$A$$ does not imply $$B$$ but $$B$$ implies $$A$$

$$A$$ implies $$B$$ and $$B$$ implies $$A$$
