MediumWhat are solid bodies composed of? Why do solid bodies stay in stable equilibrium positions?
(N/A) Solid bodies are composed of a large number of atoms or molecules arranged in a specific geometric pattern,held together by strong interatomic or intermolecular forces.
These bodies stay in stable equilibrium positions because the atoms or molecules are at a distance where the net interatomic force is zero. If an external force displaces them,the interatomic forces act as restoring forces,pulling them back to their original equilibrium positions,thereby maintaining the structural stability of the solid.
