$\pi $ mesons can be
${\pi ^ + }$ or ${\pi ^ - }$
${\pi ^ + }$ or ${\pi ^0}$
${\pi ^ - }$ or ${\pi ^0}$
${\pi ^ + },\;{\pi ^ - }$ or ${\pi ^0}$
(d) $p \to {\pi ^ + } + n,$ $n \to p + {\pi ^ – }$ and $n \to n' + {\pi ^0}$
Who invented neutron ?
If a ${H_2}$ nucleus is completely converted into energy, the energy produced will be around……….$MeV$
The ratio of mass densities of nuclei of $^{40}Ca$ and $^{16}O$ is close to
The nuclear radius is given by $R=r_0 A^{1 / 3}$, where $r_0$ is constant and $A$ is the atomic mass number. Then, the nuclear mass density of $U^{238}$ is
Confusing about what to choose? Our team will schedule a demo shortly.
