Can raise the CG of the body but cannot lower it
Tends to lower the CG of the body
Neither raises nor lowers the CG of the body
None of above
Answer is Right!
Answer is Wrong!
The correct answer is: C. Neither raises nor lowers the CG of the body.
A rigid body is in stable equilibrium if, when displaced from its equilibrium position, the net force acting on it tends to restore it to that position. This means that the center of gravity (CG) of the body must remain at the same height or lower when a force is applied.
If the CG of the body is raised when a force is applied, then the body will tend to move further away from its equilibrium position. This is an unstable equilibrium.
If the CG of the body is lowered when a force is applied, then the body will tend to move closer to its equilibrium position. This is a stable equilibrium.
Therefore, the only option that satisfies both of these conditions is C.
