The centre of mass of a body is locateda)outside the systemb)inside or outside the systemc)inside the systemd)at the centre of systemCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

The given answer is wrong.The correct answer should be both inside and outside. Still confused? No problem. Consider this- Where do you think is the centre of mass of a ring? In the geometric centre. And that centre is the point where there appears to be nothing! What about a solid disc? Like the last time, again it lies on the geometric centre. But this time it is situated on the disc.

Hope m making sense.

Answer

Option- b is wrong it can be both outside or inside as well

Answer

The centre of mass of a system can be inside or outside the system, For example for a solid circular plate it is inside and for a ring it is outside.

Answer

Correct answer is C

Answer

The centre of mass of a system can be located either inside or outside the system. For example, in a boomerang the center if mass of it is located outside its system along its axis of rotation. So the crt answer is c.

Answer

The location of centre of mass of a rigid body depends on the distribution of mass in the body and the shape of the body.For example the centre of mass(com) of a disc of uniform distribution of mass is at it's centre which is within the matter,whereas the com of a ring of uniform mass distribution lies at it's geometric centre which is outside of its matter. Thus the answer is option (c).

Answer

I think correct option is c by my knowledge .

Answer

Ans is C it may be outside or inside just example a ring the com is at centre not on body

Answer

The Centre of Mass Explained
The concept of the center of mass is crucial in understanding the distribution of mass in a physical system. Here’s a detailed explanation of why the center of mass of a body can be located either inside or outside the system.
Definition of Centre of Mass
- The center of mass is the point where the entire mass of the body or system can be considered to be concentrated for the purpose of motion.
- It is determined based on the distribution of mass within the object or system.
Location of Centre of Mass
- The center of mass can be located:
- Inside the System: For symmetrical objects like spheres or cubes, the center of mass is typically at the geometric center.
- Outside the System: For irregularly shaped bodies or systems with gaps, the center of mass may fall outside the physical material. For example, in a hollow ring, the center of mass is at the center of the ring, which is an empty space.
Factors Influencing Centre of Mass
- The shape, density, and distribution of mass greatly influence where the center of mass is located.
- In a composite system, the center of mass can shift based on the arrangement of the components.
Conclusion
- Therefore, it's correct to state that the center of mass of a body can be located either inside or outside the system (Option B). Understanding this concept is essential in fields like physics and engineering, where the behavior of objects is analyzed based on their mass distribution.

Answer

The centre of mass of a body can lie within or outside the body.
Example
(i) Centre of mass of a uniform rod lies at its geometrical centre which lies within the rod
(ii) Centre of mass of a uniform ring lies at its geometrical centre which lies outside the ring.

Answer

Oh no it should be inside.....I'd choose at the centre though
