363865 The particle \(A\) is converted into \(C\) via following reaction
\(A \to B{ + _2}H{e^4}\)
\(B \rightarrow C+2 e^{-}\)
Then

1 \(A\) and \(C\) are isobars
2 \(A\) and \(C\) are isotopes
3 \(A\) and \(B\) are isobars

363866 Two nuclei have mass number in ratio of \(1: 4\). The ratio of their nuclear densities is:

1 \(1: 4\)
2 \(1: 2\)
3 \(1: 64\)
4 \(1: 1\)
PHXII13:NUCLEI

363867 Read the Assertion and Reason carefully to mark the correct options given below:
Assertion :
The nuclear density of nuclides \(_5^{10}B,\,_3^6Li,\,_{26}^{56}Fe,\,_{10}^{20}\,Ne\) and \(_{83}^{209}Bi\) can be arranged as \(\rho_{B i}^{N}>\rho_{F e}^{N}>\rho_{N e}^{N}>\rho_{B}^{N}>\rho_{L i}^{N}\)
Reason :
The radius \(R\) of nucleus is related to its mass number \(A\) as \(R=R_{0} A^{1 / 3}\), where \(R_{0}\) is a constant.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
