An alpha particle is projected towards a stationary ${}_{92}^{235}U$ nucleus with $KE$ kinetic energy find distance of closest approach
$\frac{{K{e^2}}}{{\left( {KE} \right)}}$
$\frac{{92\,K{e^2}}}{{\left( {KE} \right)}}$
$\frac{{K{e^2}}}{{92\,\left( {KE} \right)}}$
$\frac{{KE}}{{K{e^2}}}$
Define nuclear force.
The mass of a neutron is the same as that of
The ratio of radii of nuclei $_{13}A{l^{27}}$ and $_{52}{X^A}$ is $3 : 5$. The number of neutrons in the nuclei of $X$ will be
How is an atom represented ? Why?
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.
