Homework Statement
A 125g pear is immersed at the bottoming of a beaker of water which is filled with 500cm3 of water. Salt of mass 30g was then completely dissolved in the water before the pear begins to float (assume no change In Volume of the water ) given the density of pure water is 1 g /cm2
1. What is the density of the pear
2.claculate the buoyant force Acting on the pear before Saltwas added
3. Initially , what was the apparent weight of the pear in the bottom of the beaker?
4.how mush of the pear would float above the water if 100g of salt was dissolved in the water instead?
Homework Equations
Density=mass/volume
Buoyant force pvg
Apparent weight = true weight - buoyant force
The Attempt at a Solution
I can't find the volume of the pear [/B]
