# Archimedes Principle

## Homework Statement

a 6500kg iceberg is afloat in the sea. the icebergs density is 930kg/m^3 and the sea water has density of 1030kg/m^3
a) find the buoyant force on the iceberg
the volume of water displaced and the fraction of the icebergs volume that is below the waterline.

## Homework Equations

F_B=x_displaced=rho g V

## The Attempt at a Solution

i have no idea how to do this i thought that maybe since its not sinking its in equilibrium relative to something but i have no idea if thats even right or not.. thanks for any help in advance.

You are on the right track. It is pulled down by gravity, and pushed up by buoyancy - these are two forces in equilibrium. One of these is very easy to calculate from the data given - that gives you the other one (they are in equilibrium, which means they are identical).

ok thank you i cant believe i missed that - problem solved thanks to you and PF!!
