Direction for: In each of the following questions a statement of Assertion is given followed by a corresponding statement of Reason just below it. Of the statements mark the correct answer as
Assertion: Energy is released in nuclear Fission. Reason: Total binding energy of the fission fragments is larger than the total bind energy of the parent nucleus.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 both assertion and reason are false.
Correct Answer: A
Solution :
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 Einsteins mass 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 increase. Note: This phenomenon is the basis of nuclear bombs and nuclear reactors.
