The activity of a certain radioactive sample is plotted against time in graph. If the initial slope of the curve is m, then find the slope of the curve at point P ? |

Answer» <P> Solution :Activity `A=A_0 e^(-lambdat)`Slope of the graph is `(dA)/(dt)=-lambdaA_0e^(-lambdat)` Initially `t=0 RARR (dA)/(dt)=-lambdaA_0` (=m) given Slope of POINT P is , `(dA)/(dt)=-lambdaA_0 e^(-lambdatau)` `=m/3 [ because lambdatau=1]` |
