NEET Physics Nuclear Fusion MCQ Question
Imagine a diagram showing two deuterons approaching each other to undergo nuclear fusion. Which of the following is necessary for these deuterons to successfully combine and form a new nucleus?
Overcoming the Coulomb barrier by achieving sufficient kinetic energy.
Being at a temperature below 10^3 K to reduce repulsion.
Having an equal number of neutrons and protons to balance forces.
Being in a liquid state to facilitate closer contact.
Correct Answer
Detailed Explanation
For fusion to occur, deuterons must have enough energy to overcome the Coulomb barrier, which is due to their positive charges repelling each other.
