1. A 210 N object floats with three-fourths of its volume beneath the surface of the water. What is the buoyant force on the object? Newtons
Is this a trick question? I thought that in case like this.. Fb - W = 0..thus Fb = W..so shouldn't the Fb simply equal 210?
2. A lead block is suspended from the underside of a 0.2 kg block of wood of density of 716 kg/m3. If the upper surface of the wood is just level with the water, what is the mass of the lead block?(The density of lead is 11340 kg/m3)
In this case I know you can figure out the V of the wood block..would you once again use a buoyancy equation?
FB - W1 - W2 = 0..? Any help on where I should start
