Archimedes' principle can be used not only to determine the specific gravity of a solid using a known liquid; the reverse can be done as well. as an example, a 4.00-kg aluminum ball has an apparent mass of 2.10 kg when submerged in a particular liquid: calculate the density of the liquid in kg/m^3

derive a formula for determining the density of a liquid using this procedure.

express your answer in terms of the variables mobject, mapparent, and rhoobject.

Explanation:

Given

mass of aluminium ball

apparent mass of aluminium ball in liquid

If and is the density of object and liquid then

mass of object can be written as

where V is the volume of object

divide 1 and 2 we get

Density of aluminium is

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
