BPSC – Combined Competitive Examination · પ્રશ્ન 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
જવાબ બતાવો અને સમજૂતી

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

સમજૂતી

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

  • (A) ખોટો

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

  • (B) સાચો

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

  • (C) ખોટો

    Wrong: meaningless; gravity is what causes the fall.

  • (D) ખોટો

    Wrong: irrelevant to the energy question asked.
