प्रश्न
State two methods of increasing the stability of the body.

उत्तर
The stability off a body is increased if:
(i) The centre of gravity is as low as possible. It should be above the base and near the geometric centre of the body. This is the case when the mass of the body is large at the bottom.
(ii) The area of the base of the body is large so that the vertical line through the CG of the body passes through its base. If the body is slightly tilted, its CG rises higher and it has a tendency to regain its original position to lower the CG.
