Q. No.

Given below are two statements: 
Assertion (A): 90Sr from radioactive fallout from a nuclear bomb ends up in the bones of human beings through the milk consumed by them. It causes impairment of the production of red blood cells.
Reason (R): The energetic \(\beta\)-particles emitted in the decay of 90Sr damage the bone marrow.
  
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. Both (A) and (R) are false.

Given below are two statements: 
Assertion (A): In the process of nuclear fission, the fragments emit two or three neutrons as soon as they are formed and subsequently emit particles.
Reason (R): As the fragments contain an excess of neutrons over protons, emission of neutrons and particles bring their neutron/proton ratio to stable values.
  
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).

Given below are two statements: 
Assertion (A): If a heavy nucleus is split into two medium-sized parts, each of the new nuclei will have more binding energy per nucleon than the original nucleus.
Reason (R): Joining two light nuclei together to give a single nucleus of medium size means more binding energy per nucleon in the new nucleus.
 
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
