Q. Consider$\alpha - Particles,\beta - Particles\ and\ \gamma - rays$, each having an energy of 0.5 MeV. In increasing order of penetrating powers, the radiations are
A) $\alpha,\beta,\gamma$
B) $\alpha,\gamma,\beta$
C) $\beta,\gamma,\ \alpha$
D) $\gamma,\beta,\alpha$
Explanation
(a) In increasing order of penetrating powers, the radiations are,
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \alpha < \beta < \gamma$
