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

Hint : It is given that radium on decay gives out alpha particles. Radium consists of 88 protons and has 88 electrons, which gives out radon and alpha particles. We know the mass value of radium used in the process. Find the effect of weight in the alpha particle emission rate.

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.
