Homework Statement
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.
Homework Equations
Fb=(density of the surrounding liquid)(V)(g)
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!
