    show up thrust is 2 *10^-5 N

    tge data given diameter is 1.6 *10^-3

    volume 2.1*10^-9
    densisty of sand is 2.7 *10^3

    weight 5.7*10^weight varies in proportion to radi 5N
    show density of water is 1*10^3

    What I did up thrust = 2.1*10^-9*1*10^3 got the answer
    the mark sheme else by calculating mass then times it by 9.81

    is tht wrong

    You are unlikely to get a response unless you post a scanned copy of the full question.
