Question

In the options given below, let $E$ denote the rest mass energy of a nucleus and $n$ , a neutron. The correct option is

• A. $\left.\left.\left.E_{92}^{236} \mathrm{U}\right)>E_{53}^{137} \mathrm{I}\right)+E_{39}^{97} \mathrm{Y}\right)+2 E(\mathrm{n})$
• B. $\left.\left.\left.E_{92}^{236} \mathrm{U}\right)
• C. $\left.\left.\left.E^{236} \mathrm{U}\right)
• D. $\left.\left.\left.E_{92}^{235} \mathrm{U}\right)>E{ }_{56}^{140} \mathrm{Ba}\right)+E_{36}^{94} \mathrm{Kr}\right)+E(\mathrm{n})$

Answer 1

Answer: (A)

Rest mass of parent nucleus should be greater than the rest masses of daughter nuclei. Therefore, the option ( $$ \left.\left.\left.\left(E_{92}^{236} \mathrm{U}\right)>E_{53}^{137} \mathrm{I}\right)+E_{39}^{97} \mathrm{Y}\right)+2 E(\mathrm{n})\right) $$ will be correct.
