An object weighs 285 N in the air. When tied to a string, connected to a balance, and immersed in water, it weighs 230 N. When it is immersed in oil, it weighs 261 N.

(a) Find the density of the object.

(b) Find the density of the oil.

2. Relevant equations

A=mgd(water)

3. The attempt at a solution

this weight is equal to 285-230=55N corresponding to a density =1

so the density of the body is 285/55=5.18

the weight of oil is 285-261= 24 =Mgd(oil)

compared to water d(oil)/d(water)=24/55=0.436
