Give two examples of rigid bodies whose center of mass lies outside the material of the body.
(N/A) The center of mass of a rigid body does not necessarily have to lie within the material of the body. Examples include:
$1$. $A$ circular ring: The center of mass is at the geometric center,which is in the empty space inside the ring.
$2$. $A$ hollow cylinder: The center of mass lies on the axis of the cylinder in the empty space inside.
$3$. $A$ bangle or a photo frame: These also have their center of mass in the empty space enclosed by their structure.
