The point, through which the whole weight of the body acts, irrespective of its position is known as:

Explanation:

Center of Gravity

• The force of attraction, which is proportional to the mass of the particle, acts vertically downwards and is known as the weight of the body.
• As the distance between the different particles of a body and the center of the earth is taken as the same, therefore these forces may be taken to act along parallel lines.
• A point may be found out in a body, through which the resultant of all such parallel forces act.
• This point, through which the whole weight of the body acts is known as the Center of gravity.

Centroid

• The plane figures (triangle, quadrilateral, circle, etc) have only areas, but no mass. The center of the area of plane figures is known as Centrold.
