List of top Physics Questions on Buoyancy and Floatation asked in AP EAPCET

A block of wood of volume \(V\) floats in water with half of its volume submerged. The same block floats in an oil with \(0.8V\) volume submerged. If the density of water is \(1000\,\text{kg m}^{-3}\), then the density of the oil is

An object of mass \(10\,\text{kg}\) is released from rest in a liquid. If the object moves a distance of \(2\,\text{m}\) while sinking in a time duration of \(1\,\text{s}\), then the mass of the liquid displaced by the submerged object is \((g=10\,\text{m/s}^2)\):
