Nuclei Test - 2...

The binding energy per nucleon of $C^{12}$ is $7.68$ MeV and that of $C^{13}$  is $7.47$ Mev. The energy required to remove one neutron from $C^{13}$ is

The atomic mass of $_{7}N^{15}$ is $15.000108 amu$ and that of $_{8}O^{16}$ is $15.994915 amu$. The minimum energy required to remove the least tightly bound proton is (mass of proton is $1.007825 amu)$

If $2g$ of hydrogen is converted into $1.986 gm$ Helium in a thermonuclear reaction,  the energy released is

$_{7}N^{14} +_{2}He^{4}\rightarrow$ X+$_{1}H^{1}$ ;  X is

Bombardment of lithium with proton gives rise to the following reaction :
$^{7}_{3}Li+^{1}_{1} H \rightarrow$2($^{4}_{2}He) + Q$
The Q-value is 
(atomic masses of lithium, proton and helium are $7.016$ amu, $1.008$ amu and $4.004$ amu respectively)

The masses of neutron and proton are $1.0087$ and $1.0073$ amu respectively. If the neutrons and protons combine to form a Helium nucleus of mass $4.0015 amu$, the binding energy of the Helium nucleus will be :

A  $\gamma$ -ray photon creates an electron-positron pair. The rest mass equivalent of electron is 0.5 MeV. KE of the electron - positron system is 0.78 MeV. Then the energy of $\gamma$ -ray photon is

Assertion (A) : All the radioactive elements are ultimately converted into lead
Reason (R): All the elements above lead are unstable

Assertion (A): Binding energy per nucleon is the measure of the stability of the nucleus.

In the nuclear fusion reaction : $^{2}_{1}H+ ^{3}_{1}H \rightarrow$ $^{4}_{2}He+n$ , given that the repulsive potential energy between the two nuclei is $\sim 7.7 \times 10^{-14}$J, the temperature to which the gases must be heated to initiate the reaction is nearly 
(Boltzmann's constant $k=$1.38 x 10$^{-23}$J)
