The explosion of atom bomb is based on the principle of

State the significance of multiplication factor in nuclear reactors.

The nucleus finally formed in fusion of protons in proton-proton cycle is that of:

What is proton-proton cycle?

Find the energy released when two ${}_1{\mathrm{H}}^2$ nuclei fuse together to form a single ${}_2{\mathrm{He}}^4$ nucleus. Given, the binding energy per nucleon of ${}_1{\mathrm{H}}^2$ and ${}_2{\mathrm{He}}^4$ are $1.1 \mathrm{MeV}$ and $7.0 \mathrm{MeV}$ respectively.

In Thomson's experiment for the determination of $\left(\frac{\mathrm{e}}{\mathrm{m}}\right)$ of electron, electric field of intensity $\text{'}\mathrm{E}\text{'}$ only is applied. Now the deflection produced by the electron beam is directly proportional to:

The energy of electron in the excited state of hydrogen atom is $-0.85 \mathrm{eV}$. If $\text{'}\mathrm{h}\text{'}$ is Planck's constant, the angular momentum of electron in the excited state is:

Velocity of electron in Bohr's first orbit of hydrogen atom is in order of
