In the nuclear reaction $_{92}{U^{238}}{ \to _z}T{h^A}{ + _2}H{e^4}$, the values of $A$ and $Z$ are
$A = 234, Z = 94$
$A = 234, Z = 90$
$A = 238, Z = 94$
$A = 238, Z = 90$
The nuclear force between two nucleons is explained by
The radius of germanium $(Ge)$ nuclide is measured to be twice the radius of ${}_4^9Be$ . The number of nucleons in $Ge$ are
The force acting between proton and proton inside the nucleus is
Assertion : The binding energy per nucleon, for nuclei with atomic mass number $A > 100$, decreases with $A$.
Reason : The nuclear forces are weak for heavier nuclei.
The volume occupied by an atom is greater than the volume of the nucleus by a factor of about
