Energy is released in nuclear fission.
Total binding energy of the fission fragments is large than the total binding energy of the parent nucleus.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false
D. If assertion is false but reason is true.

Answer

A

Explanation

(a) When atoms of an element are bombarded by neutrons, the atomic nuclei are disintegrated and emit lighter particles. This process is called nuclear fission. The mass of the nuclei obtained by fission is less than the mass of the disintegrated nucleus and lost mass reappears in the form of heat according to Einsteinmass energy relation. The total binding energy of the fission fragments is larger than the total binding energy of the parent nucleus, because fission occurs when total mass energy decreases that is `Delta E_(bn)` will decrease.
