JEE Advanced2007PhysicsNuclear PhysicsActual
In the options given below, let E denote the rest mass energy of a nucleus and n a neutron. The correct option is
Options
- AE ( ₉₂²³⁶ U )>E ( ₅₃¹³⁷ I )+E ( ₃₆⁹⁷ Y )+2 E(n)
- B.E ₉₂²³⁶ U ) < E ( ₅₃¹³⁷ I )+E ( ₃₉⁹⁷ Y )+2 E(n)
- CE ( ₉₂²³⁶ U ) < E (5₅₆¹⁴⁰ Ba )+E ( ₃₆⁹⁴ Kr )+2 E(n)
- 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.
