Record your observations as shown below: Weight of sinker in water = x gf Weight of sinker in water + cork in air = y gf Weight of cork in air = (y - x) gf Weight of cork + sinker in water = z gf Upthrust on cork in water = (y - z) gf The ..

Buoyancy - A cork is pushed down into water kept in a glass. We find that as soon as it is released, the cork rises on its own and comes to the surface. Pressure pushes cork upwards To keep it beneath the surface of water, we have to exert downward force. This means that, when t..

R.D = Since weight is proportional to mass R.D When a body is immersed in water, it displaces its own volume of water. Upthrust on the body is equal to the weight of this displaced volume of water, which is also equal to loss of weight of the body...
