Consider the following statements A and B . Identify the correct...

Consider the following statements AA and BB. Identify the correct choice in the given answer. A. p−n,p−pp-n, p-p and n−nn-n forces between nucleons are not equal and charge dependent. B. In nuclear reactor the fission reaction will be in accelerating state if the value of neutron reproduction factor A>1A>1.

Options

  1. ABoth A and B are correct
  2. BBoth A and B are wrong
  3. CA is wrong and B is correct
  4. DA\mathrm{A} is correct and B\mathrm{B} is wrong

Correct answer

C. A is wrong and B is correct

Step-by-step solution

The force acting between proton-neutron (p−n)(p-n) proton-proton (p−p)(p-p) and neutron-neutron (n−n)(n-n) are always equal and charge independent, so statement AA is wrong. If reproduction factor of neutron (A)>1(A)>1, then fission reaction will be in accelerating state, so statement BB is correct.
