Force balance

    I am checking to see if my thought process is correct for the problem below along with my work.

    I didn't check all your numbers, but your approach looks good. The rope tension plus the bouyancy force must equal the weight. I don't know why the problem calls the 20.9 N tension force as "F_net". The net force on the crown is zero. 20.9 N is the applied force required to keep the obect from sinking.
