In a fission reaction The binding energy per nucleon of X and Y is 8.5 Me V where as of 236 U is 7.6 MeV. The total energy liberated will be about (a) 2000 MeV (b) 200 MeV (c) 2 MeV (d) 200 keV

(b)

Binding energy

=      117 × 8.5 + 117 × 8.5 - 236 × 7.6

=      234 × 8.5 - 236 × 7.6

=      1989 - 1793.6 = 200 MeV·

Thus, in per fission of Uranium nearly 200 MeV energy is liberated
