A spring dynamometer hangs an object and submerges it in water. The indication is 6N. The gravity of draining water is 4N. The gravity of the object is 10N. If it is immersed in kerosene, the buoyancy it receives will be (reduced) Why is it smaller? The density of the liquid decreases, but the volume of the liquid displaced by the object increases. Don't the two counteract each other?

In the title, it is said that the spring dynamometer hangs an object and submerges it in the water, which means that the volume of the discharged liquid is the volume of the object. When it is placed in kerosene, due to the decrease of density, the volume of the discharged liquid remains unchanged, so the buoyancy decreases
