    sir why did you take N(0) =51 and Sir what is istopic ratio ?and the answer range is 3.55-3.65

    eduncle-logo-app

    if you take value of ln2 = 0.7 then your answer come in range.second because the ratio of the two isotope is 50.it means if we take potassium be 50x then argon is x .whole potassium is decay into argon,total no.of atom is constant so any time total no.of atom is sum of two so we take N(0)=51.

    eduncle-logo-app

    isotopic ratio is the ratio of two isotope at any instant

    eduncle-logo-app

    I had take ln2=0.693 you should take ln2=0.7

    eduncle-logo-app

    you should consider this example then you better understand

    eduncle-logo-app

    the total at initial time is equal to the sum of two decay isotope at any instant

    eduncle-logo-app

    after that which portion especially you have doubt

    eduncle-logo-app

    I think you should skip now .Go ahead

    eduncle-logo-app

    sir please check this one as well

    eduncle-logo-app

    my way is also correct ,there is not only one method to solve a problem

    eduncle-logo-app

    this method is also the same as I did

    eduncle-logo-app

    N(t ) =50 wala part bata dijiye

    eduncle-logo-app

    at time t the ratio of k/Ar is 50 it means that amount of potassium remain in the decaying process is 50 out of total amount of potassium initially taken

    eduncle-logo-app

    N(t) means the amount remain at time t

    eduncle-logo-app

    N(t) means the amount remain at time t

    eduncle-logo-app

    the solution you posted and my solution both have same equation at end

    eduncle-logo-app

    sir understood thank you

    eduncle-logo-app

    you should accept this answer

    eduncle-logo-app

    sir do not delete the example you shared.

    eduncle-logo-app

    the amount of potassium is 50 times argon at time t
