    The ratio of ioning power of\[\alpha \]and\[\beta \]particle emitted from a radioactive element will be

    A)  1 : 100          

    B)  100 : 1

    C)  1000 : 1         

    D)  1 : 1000

    Correct Answer: B

    Solution :

     lonisation power of\[\alpha -\]rays is 1000 times of ionisation power of \[\gamma -\]rays while ionization power of\[\gamma -\]rays is 100 times that of \[\gamma -\]rays. \[\alpha :\beta =10,000:100\] \[=100:1\]
