NEET Physics Nuclear Fusion Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Coulomb barrier height for two protons | (i) ~ 400 keV |
| (b) Temperature for controlled fusion reactors | (ii) 10^8 K |
| (c) Fusion product of deuterons | (iii) Triton and Proton |
| (d) Age of the Sun | (iv) 5 billion years |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-i, d-ii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
The height of the Coulomb barrier for two protons is approximately 400 keV (a-i). Controlled fusion reactors operate at temperatures around 10^8 K (b-ii), and when deuterons fuse, they form a triton and a proton (c-iii). The estimated age of the sun is about 5 billion years (d-iv).
