Question

What is Buoyancy?
When a cork floats while on iron nail immerses in water. Why?​

Answer 1

Buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.A cork floats in water while the iron nail sinks because the density of cork is less than that of water.

Answer 2

1. The upward force exerted by fluids (liquid and gas) on objects when they are immersed in them is called buoyant force and the phenomenon is called buoyancy
2. A cork floats in water while the iron nail sinks because the density of cork is less than that of water
