Question

A body of mass M while falling vertically downwards under gravity breaks into two parts, a part B of
mass M 3 and body C of mass 2 M 3. The centre of mass of the bodies B and C taken together
(a) does not shift
(b) shifts towards body B
(c) shifts towards body C
(d) depends upon height of breaking​

Answer 1

Answer:

depends upon inthe height of breaking

Answer 2

Answer:

a) doesn't shift in either of b or c

Explanation:

It's because from the concept of inertia, there is no displacement of center of masses of body if no external unbalanced force is applied. Since the body separated due to some internal force, there will not be change in center of mass with respect to B and C . Instead the center of mass will come down experiencing vertical downward gravitational force.

Hope,this will help you!!..Have a nice day:-)
