Paragraph: Scientists are working hard to develop nuclear fusion reactor. Nuclei of heavy hydrogen, ₁^2 H known as deuteron and denoted by D can be thought of as a candidate for fusion reactor. The D - D reaction is ₁^2 H + ₁^2 H ₂^3 He +n+ energy. In the core of fusion reactor. A gas of heavy hydrogen is fully ionized into deuteron nuclei and electrons. This collection of ₁^4 H nuclei and electrons is known as plasm

Options

  1. A1.0 10^9 ~K < T < 2.0 10^9 ~K
  2. B20 10^9 ~K < T < 3.0 10^9 ~K
  3. C3.0 10^9 ~K < T < 4.0 10^9 ~K
  4. D4.0 10^9 ~K < T < 5.0 10^9 ~K

Correct answer

A. 1.0 10^9 ~K < T < 2.0 10^9 ~K

Step-by-step solution

From conservation of mechanical energy, we have gathered U_i+K_i=U_f+U_f 0+2(1.5 k T)= 1 4 ₀ (e)(e) d +0 gathered Substituting the values, we get T=1.4 10^9 ~K
