Question

Can a body rotate about its centre
of gravity under the action of its weight?​

Answer 1

Answer:

No, body can not rotate about its center of gravity because center of gravity is point about which whole weight of body act ( where the weight is balance ) . The line passing through the axis of rotation the torque acting is zero .

Answer 2

Answer:

No, a body cannot rotate about its center of gravity under the action of its weight.

Explanation:

Center of gravity is an imaginary point in a body of matter where the total weight of the body may be thought to be concentrated.

The point of intersection of lines of action of weight of all points of body is referred to as center of gravity.

Hence, a body can not rotate about its center of gravity as center of gravity is point about which whole weight of body act or we can say that the weight is balanced.

Also, the line passing through the axis of rotation the torque acting is zero .

Hence, a body cannot rotate about its center of gravity under the action of its weight.
