Homework Statement
A 6cm tall cylinder floats in water with its axis perpendicular to the surface. The length of the cylinder above water is 2cm. What is the cylinders mass density?
Homework Equations
Fb-Fg = pf*vf*g = mo*g
=pf*vf*g = po*vo*g
mass density = p = m / V
*note: pf=density of fluid
vf= volume of fluid
mo = mass of object
vo = volume of object.
water density = 1000 kg/m^3
The Attempt at a Solution
I basically drew the Free body diagram which had the buoyuant force pointing up and force of object pointing down to due (mg). Help! An answer would be nice
