Q177 / 200 · TS EAMCET 2002 · Physics

Consider the following statements $A$ and $B$. Identify the correct choice in the given answer. A. $p-n, p-p$ and $n-n$ 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 $A>1$.

  • A
    Both A and B are correct
  • B
    Both A and B are wrong
  • Correct answer
    C
    A is wrong and B is correct
  • D
    $\mathrm{A}$ is correct and $\mathrm{B}$ is wrong

Solution

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

Hence, the correct answer is option: 'C'.
