Explanation:When external force is applied on the solid bodies, the solid bodies get deformed. The atoms or molecules are displaced from their equilibrium positions causing a change in the interatomic ( or intermolicular ) distances. When the deforming foce is removed, the interatomic forces tend to drive them back to their original postions. Thus the body regains its original shape and size.

Elasticity is the property of a body, by virtue of which it tends to regain its original size and shape when the applied force is removed.

Explanation:
Elasticity is a property of materials that allows them to deform when a force is applied and then return to their original shape and size when the force is removed. This property is crucial in various fields such as engineering, physics, and materials science.

Key Points:
- Elasticity is the ability of a body to undergo deformation (change in shape or size) under the influence of an external force and return to its original shape and size when the force is removed.
- Elasticity is a fundamental property of materials and is related to the arrangement and behavior of atoms and molecules within the material.
- When a force is applied to an elastic material, it causes the atoms or molecules to move from their equilibrium positions, resulting in a temporary change in shape or size.
- The material stores the energy from the applied force in the form of potential energy, which enables it to return to its original shape and size once the force is removed.
- The restoring force that allows the material to regain its original shape and size is due to the intermolecular or atomic forces within the material.
- The magnitude of the deformation experienced by an elastic material is directly proportional to the applied force within the elastic limit. This relationship is described by Hooke's Law.
- If the applied force exceeds the elastic limit of the material, it may undergo permanent deformation or even fracture.
- Elastic materials exhibit a linear relationship between stress (force per unit area) and strain (deformation per unit length) within the elastic limit, which is represented by the elastic modulus or Young's modulus.

Conclusion:
In conclusion, elasticity is the property of a body that allows it to regain its original size and shape when the applied force is removed. It is a fundamental property of materials and is essential in various applications where materials need to withstand forces and deformations without undergoing permanent damage.

Attempt All Questions sub parts from each question.Elasticity vs. plasticity: Objects get deformed when pushed, pulled, and twisted. Elasticity is the measure of the amount that the object can return to its original shape after these external forces and pressure are removed. The opposite of elasticity is plasticity. When something is stretched, and it stays stretched, the material is said to be plastic. Such deformation is said to be plastic deformation. In elastic deformation, atoms of the material are displaced temporarily from their original lattice site. They return back to their original position after the removal of external force. In plastic deformation, atoms of the solid are displaced permanently from their original lattice site. They don’t return back to the original position even after the removal of external load. So, elastic deformation is temporary, whereas plastic deformation is permanent. Amount of elastic deformation is very small. But the amount of plastic deformation is quite large. External force required for elastic deformation of solid is quite small. Force required for plastic deformation is much higher. Total energy absorbed by the material during elastic and plastic deformation region is called modulus of toughness. Energy absorbed by the material during elastic deformation is called module of resilience. Most materials have an amount of force or pressure for which they deform elastically. If more force or pressure is applied, then they undergo plastic deformation. Materials those have a fair amount of plastic deformation before breaking are said to be ductile. Materials those can't stretch or bend much without breaking are said to be brittle. Copper, aluminium etc. are ductile materials. For this reason those are used for making wires. Glass and ceramics are often brittle; they will not bend; they will break.Q. Which of the following statement is false?
