The mass number of an iodine nucleus and a polonium nucleus is $125$ and $216$ respectively. The ratio of radius of iodine nucleus to that of polonium nucleus is

The distance between two nucleons for which the potential energy is minimum, is

What is the binding energy of ${}_{14}{}^{29}Si$ whose atomic mass is $28.976495 \mathrm{u}$

Mass of proton $=1.007276 \mathrm{u}$

Mass of neutron $=1.008664 \mathrm{u}$

(Neglect the electron mass) (Assume $1 \mathrm{u}=931.5 \mathrm{MeV}$)

In one average lifetime of a radioactive nucleus,

An active nucleus decays to one-third $\left(\frac{1}{3}\right)$ in $20 \mathrm{Hrs}.$ The fraction of original activity remaining after $80 \mathrm{Hrs}$ is

The scientific principle that forms the basis of the Tokamak technology is

In a nuclear reactor, the main purpose of the moderator is to

If $5 \mathrm{mg}$ of ${}^{235}U$ is completely destroyed in an atom bomb, then approximate total energy released is (given that the energy released per fission is $200 \mathrm{MeV}$)
