| There's a force proportional to the weight of water that's been displaced by this thing and because this thing has essentially the same density as seawater, because it's made of seawater, then that force is equal and opposite to the force of gravity, | Общая плотность тела практически равна плотности соленой воды, ведь именно ею канистра и заполненна. Из-за этого, сила равна по модулю и противоположна по направлению силе тяжести. |
