Question

B. In a body of a small size, having uniform density through out the what?
of the body
coincides with the what?

​

Answer 1

Answer:

if intestinal come out side of the body through cut then the body would not able to digest the food anymore and suffer lots of pain

Explanation:

The centre of the mass is the point where the gravitational force is acting on the body. The centre of mass can also be located outside the body's mass limits, which depends on its shape. ... If the body is not with uniform density, the centre of mass (gravity) does not have to be in the geometric centre of the body.

The centre of mass can also be located outside the body’s mass limits, which depends on its shape. The centre of gravity of the triangle is in the cross-section of the angle bisections and the centre of gravity of the cube in the cross section of its diagonals. In case of irregular geometric bodies, the centre of gravity is located in the intersection of the gravity lines. This is the point that is at an average distance from all the particles of a system or individual body particle, where the total external force is acting on the particle system or the body. If a particle or body system moves under the influence of an external force, the point at which the centre of gravity is located moves as if it contains all the mass of the system or body. If the body is not with uniform density, the centre of mass (gravity) does not have to be in the geometric centre of the body. The position of the centre of gravity for the particle system in the Cartesian coordinate system is determined by the radius vector rS = Σmiri / Σmi, where mi are the masses of the particles, and ri are the radius vectors of the particles. The position of the centre of the mass of the rigid body in the Cartesian coordinate system is determined by the radius vector rS = (∫rρdV) / M, where r is the unit vector, ρ is the body’s density, V volume, and M is the mass of the body.
