Question

what is upthrust due to liquid? in short but actual

Answer 1

An object will float if its density is less than the density of the liquid it is placed into. A force called upthrustacts on all objects placed in a liquid. This force is due to the pressure in theliquid. The weight of a floating object is exactly balanced by the upthrust.

Answer 2

The effect of upthrust is that weight of the body immersed in a liquid appears to be less than its actual weight. There are two factors on which upthrust depends - Volume of the body and Density of the Liquid. Larger the volume of body submerged in liquid, greater is the upthrust.
