Time period of oscillation of a pole floating...
A pole is floating in a liquid with 80cm of its length immersed. It is pushed down a certain distance and released. What is its time period of vertical oscillation?
I think the information given is insufficient. They should have given full length of the rod or area of its cross section.
When displaced by a small distance x, restoring force, ma=Vρg=Axρg
w2=Aρg/m=Aρg/ALσ, where L is the full length of the rod and σ is its density. I can't proceed any further without knowing the values.
The answer given is 4π/7 s.
