1)A round fishing bobber floats with 25% of its volume below the water. The boober has a radius 2.0 cm. Initially, the fishing lines are slack, and make no forces on the bobber. The weight of the hook, line, and bait is negligible. a) How large is the bouyant force on this bobber? b) If a fish bites and pulls the bobber completely under water. What's the minimum downward pulling force applied by the fish to the bobber?
