NEET Physics Nuclear Fusion Assertion Reason Question
Assertion (A): Nuclear fusion in stars requires extremely high temperatures. | Reason (R): High temperatures enable nuclei to overcome the Coulomb barrier by providing them with sufficient kinetic energy.
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
Both the assertion and the reason are true. The high temperatures provide the necessary kinetic energy for nuclei to overcome the Coulomb repulsion, as explained in the NCERT context about nuclear fusion.
