Solution

The correct option is A $γ, β, α$
$\begin{matrix} Gamma ray are the most penetrating of all the radiation. Beta radiation is more penetrating than alpha radiation. so; γ > β > α (Penetration power) \end{matrix}$

Q. lf

α, β, γ

are the roots of

x^{3} + 2 x - 3 = 0

, then the transformed equation having the roots

\frac{α}{β} + \frac{β}{α}, \frac{β}{γ} + \frac{γ}{β}, \frac{γ}{α} + \frac{α}{γ}

is obtained by taking

x =

Mark the correct decreasing order of penetrating power of α particle, β particle and γ rays, each having an energy of 0.4 MeV.

The correct option is A γ,β,α Gamma ray are the most penetrating of all the radiation. Beta radiation is more penetrating than alpha radiation. so; γ>β>α (Penetration power)
