An object completely immersed in kerosene is subject to a buoyant force of 2 kN. what will be the maximum buoyancy force acting on it a) in water b) in alcohol?
Let us determine what the volume of the object will be equal to, which was completely immersed in kerosene, when from the condition of the task we know that the buoyant force that acts on it is 2 kN:
Fa = V * p * g;
pk = 800 kg / m3;
V = 2000: 10: 800 = 0.25.
Let us determine how many newtons the buoyant force will express, which will act on this body when fully immersed in water:
pw = 1000 kg / m3;
0.25 * 10 * 1000 = 2500.
Answer: 2500 N.
Let us determine how many newtons the buoyant force will express, which will act on this body when completely immersed in alcohol:
pс = pк;
Fak = Fac.
Answer: 2000 N.
