DETAILS
The solution runs as follows. Let
be the weight of the ball and
be the buoyancy force. Then
.
Let the volume of the ball be
(where
is the radius),
be its density
), and
be the acceleration due to gravity
).
The weight of the ball is given by the product of the volume, density, and
:
The buoyancy force is given by the weight of water displaced, which is the product of the volume under water and the density of water
:
,
where
is the depth to which ball is submerged.
Therefore, with the specific gravity of the ball
, we have
, or
.
