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

Options

A. `E(._(9)^(236)U) gt E(._(53)^(137)I)+E(._(39)^(97)Y)+2E(n)`
B. `E(._(9)^(236)U) lt E(._(53)^(137)I)+E(._(39)^(97)Y)+2E(n)`
C. `E(._(92)^(236)U) lt E(._(56)^(140)Ba)+E(._(36)^(94)Kr)+2E(n)`
D. `E(._(92)^(236)U) = E(._(56)^(140)Ba)+E(._(36)^(94)Kr)+2E(n)`

Answer

A

Explanation

(a) Rest mass energy of `U` will be greater than the reat mass energy of nuclei into which it breaks. The consistituent nuclei and neutrons will have kinetic energy also, as a result of conservation of linear momentum.
