Question

list the centre of gravity of some symmetrical object​

Answer 1

Explanation:

The center of gravity is the average location of the weight of an object. We can completely describe the motion of any object through space in terms of the translation of the center of gravity of the object from one place to another, and the rotation of the object about its center of gravity if it is free to rotate.

Answer 2

Center of gravity of a square is at its center
Center of gravity of a uniform rod is at its center
Center of gravity of uniform cylinder is at its median
Center of gravity of sphere is also at its center
