A 100ml solution having activity 50 dps ...

A 100ml solution having activity 50 dps is kept in a beaker It is now constantly diluted by adding water at a constant rate of `10ml//sec` and `2 ml//sec` of solution is constantly being taken out. Find the activity of 10 ml solution which is taken out, assuming half life to be effectively very large :

A

`10[1-(2/7)^(1//4)]`

B

`10[1-(5//7)^(1//2)]`

C

`50[1-(5/7)^(1//4)]`

D

`50[1-(2/7)^(1//2)]`

A 100 ml solution of a radioactive material has activity A_(0) . The solution is kept in a container and is diluted by adding water at a constant role of 100ml/sec. From a small hole in the container 20ml/sec of solution is taken out simultaneously. find the activity of the 100ml solution that is taken out in 5sec. Assume that the half life of radioactive material is very large and that the solution alwyas remains homogeneous.
