A 13.0kg block of metal is suspended from a scale and immersedin water. The dimensions of the block are 12cm x 9.5cm x9.5cm. The 12cm dimension is vertical and the top of theblock is 5cm below the surface of the water.
A. What are the forces exerted by water on top and bottom ofthe block? Don't ignore effect of air above water. P0=1.013x10 tothe 5.
B. What is reading of spring scale?
C. Show that buoyant force is equal to difference betweenforces at top and bottom.
I know that Ftop=P0 + (p of water x g x h of top) &Fbottom=P0 + (p of water x g x h of bottom) but I don't know what pof water is & what to use for h.
