A copper block is suspended from a spring balance and the balance reads 0.200 N. (The balance can be read to the nearest .001 N.) The block is then completely submerged in water.
(a) What is the mass of the block?
HINT: Notice that the block is being weighed in the figure on the left.
kg
(b) What is the volume of the block? (The density of copper is 8.92 103 kg/m3.)
NOTE: You may enter m^3 for m3
(c) What is the buoyant force experienced by the block when it is completely submerged?
HINT: Think about Archimedes' definition of buoyant force.
(d) What will the balance read when the block is completely submerged?
NOTE: The balance reads tension.
