NEET Physics Nuclear Fusion Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): Nuclear fusion in stars requires extremely high temperatures. | Reason (R): At high temperatures, nuclei can overcome the Coulomb repulsion due to their increased kinetic energy.
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 states that controlled thermonuclear fusion requires heating the nuclear fuel to temperatures in the range of 10^8 K to overcome Coulomb repulsion, confirming both the assertion and the reason.
