The atomic mass of an element $_{10}\text{X}^{20}$ is $198170\text{ amu}$. The binding energy per nucleon of that element is: (Given mass of neutron $= 00867\text{ amu}$, mass of proton $= 00783\text{ amu}$, and $1\text{ amu} = 931\text{ MeV}$)}

If the ratio of the nuclear radii of two atoms is $2:3$, then the ratio of their mass numbers is:

The main function of cadmium rods used in a nuclear reactor is to:

When \({}^{10}_{5}\text{B}\) nuclei are bombarded by neutrons, one of the resultant nuclei is \({}^{7}_{3}\text{Li}\). Then the emitted particle will be:

Radium having mass number \(200\) and binding energy per nucleon \(5.6\,\text{MeV}\), splits into two fragments Cadmium of mass number \(112\) and Hassium of mass number \(108\). If the binding energy per nucleon for Cadmium and Hassium is approximately \(8.0\,\text{MeV}\), then the energy \(Q\) released per fission will be:

If the mass numbers of two nuclei are in the ratio \( 5 : 2 \) and their diameters are in ratio \( 2 : 6 \). Then their nuclear densities will be in the ratio

The nucleus of oxygen atom contains 8 protons and 8 neutrons. What is the mass defect in amu? [Given Mass of proton = 1.00727 amu Mass of neutron = 1.00866 amu and the mass of oxygen nucleus = 15.99053 amu.]

Fusion reaction is more energetic than fission reaction because
