Assume that the nuclear binding energy per nucleon $(B/A)$ versus mass number $(A)$ is as shown in the figure. Use this plot to choose the correct choice $(s)$ given below

$(A)$ Fusion of two nuclei with mass numbers lying in the range of $1 < A < 50$ will release energy

$(B)$ Fusion of two nuclei with mass numbers lying in the range of $51 < A < 100$ will release energy

$(C)$ Fission of a nucleus lying in the mass range of $100 < A < 200$ will release energy when broken into two equal fragments

$(D)$ Fission of a nucleus lying in the mass range of $200 < A < 260$ will release energy when broken into two equal fragments

If radius of the $^{27}_{13}Al$ nucleus is taken to be $R_{Al}$, then the radius of $^{125}_{53}Te$ nucleus is nearly

In the nuclear reaction $_{92}{U^{238}}{ \to _z}T{h^A}{ + _2}H{e^4}$, the values of $A$ and $Z$ are

If the total binding energies of ${ }_1^2 H ,{ }_2^4 He ,{ }_{26}^{56} Fe$ and ${ }_{92}^{235} U$ nucleiare $2.22,28.3,492$ and $1786 MeV$ respectively, identify the most stable nucleus of the following.

Define the different terms used for the composition of a nucleus.
