Which of the following statement is correct regarding the energy required to overcome the Coulomb barrier in a nuclear fusion reaction compared to the energy produced?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1No input energy is required because nuclear fusion is a spontaneous process at room temperature.
- 2Overcoming the Coulomb barrier requires negligible energy compared to the output energy.
- 3The energy required to overcome the barrier is always exactly equal to the energy released.
- 4The input energy required to overcome the barrier is historically greater than the energy released, though modern ignition milestones have achieved a net gain.✓
Correct answer
The input energy required to overcome the barrier is historically greater than the energy released, though modern ignition milestones have achieved a net gain.
