Nuclei Test - 3...

Let $$E_1$$ and $$E_2$$ be the binding energies of two nuclei A and B. It is observed that two nuclei of A combine together to form a B nucleus. This observation is correct only if

If the Q value of an endothermic reaction is $$11.32 MeV$$, then the minimum energy of the reactant nuclei to carry out the reaction is (in laboratory frame of reference)

According to Bohr's Theory of hydrogen atom, the product of the binding energy of the electron in the $$nth$$ orbit and its radius in the $$nth$$ orbit

The Sun's mean density is

An element A decays into an element C by a two-step process:
$$A\rightarrow B+He_2^4$$ and $$B\rightarrow C+{ 2e }_{ -1}^{ 0 }$$.Then

$$_{92}U^{238}$$ absorbs a neutron. The product emits an electron. This product further emits an electron. The result is

The minimum frequency of a $$\gamma$$-ray that causes a deuteron to disintegrate into a proton and a neutron is $$(m_d=2.0141 amu, m_p=1.0078 amu, m_n=1.0087 amu.)$$

During a nuclear fusion reaction

$$^{22}Ne$$ nucleus, after absorbing energy, decays into two $$\alpha$$-particles and an unknown nucleus. The unknown nucleus is

Binding energy per nucleon for $$C^{12}$$ is 7.68 MeV and for $$C^{13}$$ is $$7.74 MeV$$. The energy required to remove a neutron from $$C^{13}$$ is
