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

Options

  1. AE ( ₉₂²³⁶ U )>E ( ₅₃¹³⁷ I )+E ( ₃₆⁹⁷ Y )+2 E(n)
  2. B.E ₉₂²³⁶ U ) < E ( ₅₃¹³⁷ I )+E ( ₃₉⁹⁷ Y )+2 E(n)
  3. CE ( ₉₂²³⁶ U ) < E (5₅₆¹⁴⁰ Ba )+E ( ₃₆⁹⁴ Kr )+2 E(n)
  4. DE (9₉₂²³⁶ U ) < E (5₅₆¹⁴⁰ Ba )+E ( ₃₆⁹⁴ Kr )+2 E(n)

Correct answer

A. E ( ₉₂²³⁶ U )>E ( ₅₃¹³⁷ I )+E ( ₃₆⁹⁷ Y )+2 E(n)

Step-by-step solution

Rest mass of parent nucleus should be greater than the rest mass of daughter nuclei. Therefore, option (a) will be correct.
