Nuclear fission is best explained by
[$AIPMT$ $2000$]

The Sun radiates energy continuously and maintains its brightness because:

On average,how many neutrons are released from the fission of a single $U^{235}$ nucleus?

By which process is the energy released from the Sun?

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 a nuclear reactor,the fission reaction will be in an accelerating state if the value of the neutron reproduction factor $k > 1$.

In the Sun,the important source of energy is
