A) \[\alpha ,\beta ,\gamma \]
B) \[\alpha ,\gamma ,\beta \]
C) \[\beta ,\gamma ,\alpha \]
D) \[\gamma ,\beta ,\alpha \]
Correct Answer: A
Solution :
Penetrating power depends upon velocity which is\[\sqrt{\frac{2K}{m}}\]. Thus, in increasing order of penetrating powers, the radiations are \[\alpha ,\,\,\beta ,\,\gamma \]
