Physics-Nuclear Fusion

NEET Physics Nuclear Fusion Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 12

Assertion (A): Nuclear fusion requires extremely high temperatures to overcome the Coulomb barrier between nuclei. | Reason (R): The high temperature ensures that the nuclei have sufficient kinetic energy to overcome the Coulomb repulsion.

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 statement that nuclear fusion requires high temperatures is true because such temperatures give nuclei the necessary kinetic energy to overcome the Coulomb barrier, as noted in the NCERT context about fusion needing enough energy to overcome repulsion.
