Embibe Experts Solutions for Chapter: Nuclear Physics, Exercise 2: Exercise-2

The dynamic mass of electron having rest mass $m_0$ and moving with speed $0.8c$ is

Helium nuclei combine to form an oxygen nucleus. The energy released in the reaction is if $m_{\mathrm{O}}=15.9994 \mathrm{amu}$ and $m_{\mathrm{He}}=4.0026 \mathrm{amu}$

If $M\left(A, Z\right)$, $M_p$ and $M_n$ denote the masses of the nucleus $AX$, proton and neutron respectively in units of $u\left(1u=931.5 \mathrm{MeV} {\mathrm{c}}^{-2}\right)$ and $BE$ represents its binding energy in $\mathrm{MeV}$, then

${{}_6\mathrm{C}}^{11}$ undergoes a decay by emitted $\beta^{+}$ then write its complete equation Given the mass value of $m\left(6^{11}\right)=11,011434u_{1}m\left({}_5{B}^{11}\right)=11.009305u$$m_{\theta }=0.000548u$ and $1\mathrm{u}=931.5\mathrm{MeV} {\mathrm{c}}^{-2}$ Calculate the Q-value of reaction.

The atomic weight of boron is $10.81$ and it has two isotopes ${{}_5\mathrm{B}}^{10}$ and ${{}_5\mathrm{B}}^{11}$ in nature would be

Assertion: In spontaneous fission, the energy is always released.

Reason: Spontaneous fission occurs to lower the binding energy of reactant nuclei.

Assertion: The density of all the nuclei is the same.

Reason: The radius of the nucleus is directly proportional to the cube root of mass number.

Assertion: Isobars are the element having same mass number but different atomic number.

Reason: Neutrons and protons are present inside the nucleus.
