JEE Main2005PhysicsCenter of Mass, Momentum and CollisionActual

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

Options

  1. Adepends on height of breaking
  2. Bdoes not shift
  3. Cbody C
  4. Dbody B

Correct answer

B. does not shift

Step-by-step solution

No horizontal external force is acting aligned & a _ cm =0 & since v _ cm =0 & x _ cm =0 aligned
