MCQ
A stretched rubber has
  • A
    Increased kinetic energy
  • ✓
    Increased potential energy
  • C
    Decreased kinetic energy
  • D
    Decreased potential energy
✓

Answer

Correct option: B.
Increased potential energy
b
(b) Due to stretching, a potential energy is stored in the rubber band which is released on releasing the rubber. Thus, potential energy is increased.
