Question

# Two samples of radium, each of mass $1mg$ and $0.1mg$ , are taken to study the emission of alpha particles. It will be observed that:(A) Both samples will emit the same number of alpha particles.(B) $1mg$ of radium will emit 10 times the number of alpha particles per second than $0.1mg$ does.(C) Emission of alpha particles is independent of mass of the samples(D) $0.1mg$ of radium will emit 10 times more than by $1mg$ of radium

In this case it is evident that , sample weighing $1mg$ will have a greater emission period than the second sample. Thus, $1mg$ will produce 10 times that of the $0.1mg$ sample.
