A downward force of 18.0 N must be applied to a woman weighing 480.0 N to keep her completely submerged in water. What is the density of her body
Fb=density of fluid times volume of fluid times g
Fb=F(bottom) minus F(top)
The Attempt at a Solution
480=18 minus f(top)
F(top)=-462 and we cant have it negative so idk what im doing wrong. Also even if it was positive, I plug it in for F=mg to solve for m and then multiply it by the volume which does not get me the density answer please help me and explain the steps!!
