प्रश्न
Draw a graph showing the variation of decay rate with number of active nuclei.
उत्तर
According to Rutherford and Soddy's law for radioactive decay = `(-dN)/(dt) = λN`
where decay constant (λ) is constant for a given radioactive material. Therefore, the graph between N and `(dN)/(dt)` is a straight line as shown in the diagram.
