Question
A body A of mass M while falling vertically downwards under gravity breaks into two parts; a body B of mass 1/3 M and a body C of mass 2/3 M. The centre of mass of bodies B and C taken together shifts compared to that of body A towards
-
depends on height of breaking
-
does not shift
-
body C
-
body B
Solution
B.
does not shift
No horizontal external force is acting
∴ = acm =0
since vcm= 0
∴∆xcm = 0
