\(M\)
floats in a container of liquid. When the block is in equilibrium,
\(20\%\)
of its volume is submerged below the surface of the liquid. A student then pushes the block down and holds it at rest so that
\(80\%\)
of its volume is submerged. What is the magnitude of the downward force that the student must exert on the block?
