Question
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.
Answers
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
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
The answer is wrong, and I am not sure why
Nvm it is correct! Thank you!
