Question

What is the main challenge mentioned in the text for initiating nuclear fusion reactions?
Options
A The difficulty in obtaining sufficient light nuclei.
B The large electrostatic energy barrier due to positive charges on the nuclei.
Correct Answer
C The lack of suitable catalysts to speed up the reaction.
D The problem of containing the fusion products.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 18 explains: "The positive charge on two nuclei coming together results in a large electrostatic energy barrier to fusion. This barrier can be overcome if one or both particles have sufficient kinetic energy to overcome the electrostatic repulsions..."

Hint

What fundamental force opposes the bringing together of two positively charged nuclei?
