Modern Physics 5 Question 8
8. In the options given below, let $E$ denote the rest mass energy of a nucleus and $n$ a neutron. The correct option is
(a) $E\left({ } _{92}^{236} U\right)>E\left({ } _{53}^{137} I\right)+E\left({ } _{39}^{97} Y\right)+2 E(n)$
(2007, 3M)
(b) $E\left({ } _{92}^{236} U\right)<E\left({ } _{53}^{137} I\right)+E\left({ } _{39}^{97} Y\right)+2 E(n)$
(c) $E\left({ } _{92}^{236} U\right)<E\left({ } _{56}^{140} Ba\right)+E\left({ } _{36}^{94} Kr\right)+2 E(n)$
(d) $E\left({ } _{92}^{235} U\right)<E\left({ } _{56}^{140} Ba\right)+E\left({ } _{36}^{94} Kr\right)+E(n)$

Answer:
Correct Answer: 8. (b)
Solution:
- Rest mass of parent nucleus should be greater than the rest mass of daughter nuclei. Therefore, option (a) will be correct.
