The gravitational force exerted on a solid object is 5.15 N as measured when the object is suspended from a spring scale. When the suspended object is submerged in water, the scale reads 4.00 N. Find the density of the object.

Answer 1

The buoyancy force in water is 1.15 N.

1.15 N = V*g*1000 kg/m^3
5.15 N = V*g*(density)
Combine the two above equations to get
density/1000 = 5.15/1.15 = 4.48
density = 4480 kg/m^3
= 4.48 g/cm^3

Answer 2

The answer is wrong, and I am not sure why
