NEET Physics Question - Modern Physics

Assertion (A): Fragments produced in the fission of \( \text{_{92}^{235}U} \) are radioactive.

Reason (R): The fragments have abnormally high proton to neutron ratio.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Fission fragments are typically neutron-rich and undergo beta-minus decay to reach stability, thus being radioactive. So (A) is true. They have a high neutron-to-proton ratio (or low proton-to-neutron ratio), not a high proton-to-neutron ratio. So (R) is false.
