NEET Physics Nuclear Fusion MCQ Question
Consider a diagram showing two deuterons approaching each other in a fusion reaction. Which of the following correctly describes the energy required for these deuterons to overcome their mutual interaction?
The deuterons must overcome the Coulomb barrier to allow the nuclear force to act.
The deuterons naturally attract each other, requiring no additional energy.
The deuterons must overcome gravitational attraction to fuse.
The deuterons require no energy to overcome any barriers.
Correct Answer
Detailed Explanation
In nuclear fusion, deuterons must have enough energy to overcome Coulomb repulsion due to their positive charges, allowing the short-range nuclear force to facilitate fusion.
