In an experiment on the transport of nutrients in the root structure of a plant, two radioactive nuclides x and y are used. initially 2.20 times more nuclei of type x are present than of type y. just three days later there are 4.55 times more nuclei of type x than of type y. isotope y has a half-life of 1.60 d. what is the half-life of isotope x?

answer is c

explanation:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
