Ну и собственно ответ )))) Based on the given assumptions and calculations, the approximate depth of the weight would be negligible or very close to the water surface. Since the drag force (0.055 N) is significantly smaller than the buoyancy force (0.328 N), the weight will not sink deep into the water. Instead, it will likely remain near the water surface or only slightly submerged. In this case, the depth can be considered to be in the order of centimeters or less, rather than meters. The weight's ellipsoid shape and small dimensions contribute to its limited submersion. Keep in mind that these results are approximate and based on the assumptions and calculations made. Actual conditions and factors may influence the exact depth of the weight.

а мне ChatGPT выдал совершенно другой ответ на аналогичный запрос )) у GPT4 получилась глубина 39.3м для свинцового шарика весом 200гр на 60 метрах лески и скорости 12 км/ч

Это был китайский GPT)

да не, ну какие 39м, хотя шарик точно более оптикаемый, но оно в жизни так не заглубится
