	A nucleus ruptures into two nuclear parts which have their velocity ratio equal to 2 : 1. What will be the ratio of their nuclear size (nuclear radius)
	Energy of 1g uranium is equal to
	In a fission reaction $_{92}^{236}U{ \to ^{117}}X{ + ^{117}}Y + n + n$, the binding energy per nucleon of X and Y is 8.5 MeV whereas of $^{236}U$is 7.6 MeV. The total energy liberated will be about
	Atomic number of a nucleus is Z and atomic mass is M. The number of neutron is
	The $\alpha$ -particle is the nucleus of an atom of
	The force acting between proton and proton inside the nucleus is
	For a nucleus to be stable, the correct relation between neutron number N and Proton number Z is
	Two nucleons are at a separation of $1 \times {10^{ - 15}}m$. The net force between them is ${F_1}$, if both are neutrons, ${F_2}$ if both are protons and ${F_3}$ if one is a proton and other is a neutron. In such a case
	${M_n}$ and ${M_p}$ represent mass of neutron and proton respectively. If an element having atomic mass M has N-neutron and Z-proton, then the correct relation will be
	If a ${H_2}$ nucleus is completely converted into energy, the energy produced will be around
