Physics-Nuclear Fusion
NEET Physics Nuclear Fusion Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
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.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
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.
