What will the scale read when the object is submerged in water?

The volume of the object is .03 cubic meters is suspended from a spring scale which reads 45.4 kg out of the water.What will the scale read when the object is submerged in water?
Wi = Wo - 蟻V = 45.4 - 1000*.03 = 15.4 kgWhat will the scale read when the object is submerged in water?
F a= d * V( F a: Archimedes gravity; d: density of the liquid; V: the volume of the part of that thing submerges)


In this way we can know the gravity of archimedes in that object is: .03 * 10.000= 300 Newton =30kg


m1=D*V=45.4kg


m2=D*V-F a=45.4 -30=15.4kg


that object in the water weighs 15.4 kg
