please tell me the approach to this sol as my method isnb't giving the right answer ! the half life of a certain radioactive element is 100 s..... find the time period in which the element shall decay into 1/6 of it's original amount of nuclei... i did this like---since half life is given..value of can be found........then from the equation N t = No e - kt i found out the value by taking log.......but this is not giving the correct answer.....moroever the question does not mention any specific value of log of any number !!
