BPSC – Combined Competitive Examination · प्रश्न 125

The potential energy of a freely falling body continuously decreases. Therefore:

  1. The principle of conservation of energy is violated
  2. The principle of conservation of energy is not violated
  3. Gravitational force is violated
  4. Gravitational force is not violated
उत्तर दाखवा आणि स्पष्टीकरण

उत्तर: (B) The principle of conservation of energy is not violated

स्पष्टीकरण

As the body falls, potential energy converts to kinetic energy; total mechanical energy is conserved.

  • (A) चूक

    Wrong: lost potential energy becomes kinetic energy, so energy is conserved.

  • (B) बरोबर

    Correct: PE + KE stays constant (ignoring air resistance).

  • (C) चूक

    Wrong: meaningless; gravity is what causes the fall.

  • (D) चूक

    Wrong: irrelevant to the energy question asked.
