Center of Mass and Collision question

2012 · Q159

NEETPhysicsCenter of Mass and CollisionMCQ+4 / −1
Two persons of masses 55 kg and 65 kg respectively, are at the opposite ends of a boat. The length of the boat is 3.0 m and weights 100 kg. The 55 kg man walks up to the 65 kg man and sits with him. If the boat is in still water the centre of mass of the system shifts by :
  1. A
    3.0 m
  2. B
    2.3 m
  3. C
    zero
  4. D
    0.75 m

Correct answer: C

AIPMT 2012 Prelims Physics - Center of Mass and Collision Question 21 English Explanation

As no external force acts on the system, therefore centre of mass will not shift.
