1. The problem statement, all variables and given/known data An object weighing 341 N in air is immersed in water after being tied to a string connected to a force scale. The scale now reads 307 N. Calculate the density of the object. 2. Relevant equations Fb=(density of the surrounding liquid)(V)(g) 3. The attempt at a solution Fb is difference in the forces, 341N-307N = 34N v = ((initial weight)-(submerged weight))/9.8 = 3.47 mass = 341N/9.8 So Density = m / v Density therefore = 10.3kg/m^3 Its wrong, i have no idea why, probably some unit conversion somewhere. thanks!
