NEET Physics Nuclear Fusion Assertion Reason Question
Assertion (A): In controlled thermonuclear fusion, achieving high temperatures is crucial for the fusion of deuterons.
Reason (R): The high temperature ensures that deuterons have enough energy to overcome the coulomb repulsion between them.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
The NCERT context indicates that high temperatures are necessary in controlled fusion to provide the energy needed for deuterons to overcome the coulomb barrier, thereby facilitating fusion.
