Problem C20:
A block is floating in a fluid. The density of the fluid is
n1. The density of the block is
n2. The top of the block is
a distance h above the surface of the fluid as shown below.
The block is given a slight push downward and oscillates up and
down at the fluid's surface. What is the period T of oscillation
of the block? If T=n3π
√h/g,
what is n3? Note that n1 and n2
have the same units of density. (The density of water
is 100 in these units.) n3 is unitless. g is the acceleration due to gravity.
