NEET Physics Nuclear Fusion MCQ Question
Which of the following statements about nuclear fusion is correct?
Nuclear fusion requires nuclei to overcome coulomb repulsion and achieve sufficient energy.
The height of the coulomb barrier is constant regardless of the charges of the nuclei involved.
Nuclear fusion can occur at any temperature without the need for high energy input.
The process of nuclear fusion does not involve the conversion of mass to energy.
Correct Answer
Detailed Explanation
Statement A is correct as it highlights the need for sufficient energy to overcome the coulomb repulsion between positively charged nuclei, which is necessary for fusion to occur. Statement B is incorrect because the barrier height depends on the charges and radii of the nuclei. Statement C is false since high temperatures are required. Statement D is also incorrect as fusion involves mass-energy conversion.
