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

A 20 g copper block is suspended by a vertical spring causing 1 cm elongation over the natural length of the spring. If a beaker of water is placed below the block so that the copper block is completely immersed in the liquid, the elongation of the spring is (Density of copper 9000 kg m\(^{-3}\), Density of water 1000 kg m\(^{-3}\), \( g = 10 \) ms\(^{-2}\)):
A body of volume \(V\) floats on water with \(\frac{1}{3}\) of its volume above the surface. Find the volume of the object above the surface when floating on a liquid of specific gravity 1.5.
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 \((g=10\,\text{m/s}^2)\):
