Question

Draw centre of gravity for regular-shaped objects​

Answer 1

The center of gravity for regular-shaped objects​ coincides with their center of mass.

• The center of gravity of an object is the point at which the weight of the object (mg) exerts no torque on the body.
• This is possible only when the center of gravity lies on the line of action of force mg.
• For uniformly shaped objects like a cube, cuboid, ring, disc, etc. the center of mass of the object coincides with the center of gravity.
• For such objects, both these points lie at the center of the object.
• For example, for a disc both the points lie on the center of the circle.
• The center of gravity for a few objects is shown below.
