Do the center of the gravity always coincide with the geometrical center of the object?

Only if the object is homogeneous, i.e. the mass is uniformly distributed. If the object is lumpy, or has thick spots and thin spots, then the center of gravity isn't related to the geometric shape.
Consider a see-saw with a light kid on one end and a heavy kid on the other end. The geometric center is the mid-point of the board, but the center of gravity is closer to the heavy kid.

What is the center of gravity for a spherical object?
If the object is homogeneous, its center of mass is in its geometrical center. And if it is small compared to Earth, its center of gravity is, for all practical purposes, its center of mass.
Where does an object center of gravity always lie?
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
Does the center of gravity of a solid body always lie within the body?
The center of gravity of a solid body does not always lie within the body. An example of this is a hula hoop. The center of gravity does not lie on the hoop that rotates.
Do the center of mass and the center of gravity coincide?
Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
What statement about Gravity is always true?
Objects will always be pulled to the center of the mass.
Who found out the geometrical center of gravity?
Newton.
Under what condition the center of mass does not coincide with the center of gravity?
If the gravity is not constant over the body.
Why does the center of gravity and center of buoyancy always not in same position?
Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide

Difference between center of mass and center of gravity?
The center of mass is a geometrical measurement not considering the weight distribution. The center of gravity is one location on a particular mass structure where the distribution of weight is the same no matter the direction of the measurement as it pertains to that one particular mass structure.
Where does an object center of gravity always lie?
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
Does the center of gravity always lies on the body?
No. For example, a ring has a center of gravity in the center of the ring, not on any part of the ring.
Does the center of gravity of a solid body always lie within the body?
The center of gravity of a solid body does not always lie within the body. An example of this is a hula hoop. The center of gravity does not lie on the hoop that rotates.

Where is the center of gravity in the five positions of the feet in ballet?
In ballet, he center of gravity should always be in the middle of your body, no matter what you are doing.
Does the center of gravity always have to be located withing an object?
No. The center of gravity of a wedding ring is in the space at the center of the ring. The center of gravity of the letter ' V ' is somewhere along the vertical line between the two slanted lines.
