Consider α\alpha -particles, β\beta -particles and γ\gamma -rays, each having an energy of 0.50 MeV. The increasing order of penetration power is :

A

α <β<γ \alpha\text{ <}\beta < \gamma\text{ }

B

α <γ<β \alpha\text{ <}\gamma < \beta\text{ }

C

β<γ<α\beta < \gamma < \alpha

D

γ<β<α\gamma < \beta < \alpha

Answer

α <β<γ \alpha\text{ <}\beta < \gamma\text{ }

Explanation

Solution

It is the order of penetrating power.
