MCQ
Elasticity is shown by materials because inter-atomic or inter-molecular forces:
  • A
    Increases when a body is deformed.
  • B
    Decreases when a body is deformed.
  • C
    Remains same when a body is deformed.
  • D
    Becomes non-zero when a body is deformed.

Answer

  1. Becomes non-zero when a body is deformed.

Explanation:

When a body is deformed, atoms/molecules are displaced from their equilibrium positions (F = 0). As a result, there is a force $(\text{F}\not=0)$ acts between them to restore their position.
