Physics-Nuclear Fusion
NEET Physics Nuclear Fusion Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): The nuclear force is responsible for allowing nuclear fusion to occur despite the repulsion between protons. | Reason (R): The nuclear force is a short-range force that can overcome the Coulomb barrier at very high temperatures.
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 nuclear force is indeed responsible for enabling fusion by overcoming Coulomb repulsion, and it is a short-range force that becomes effective when nuclei are very close, which can happen at high temperatures.
