Pressure Differences in Fluids and Upthrust

The video tutorial explores pressure differences in fluids, starting with the equation P = h * rho * g, where P is pressure, h is depth, rho is density, and g is gravitational field strength. It demonstrates how pressure increases with depth using a diver example, calculating pressure changes at different depths. An alternative calculation method is introduced for efficiency. The tutorial then examines the consequences of pressure differences, focusing on upthrust and its role in floating objects. It concludes by discussing the balance between weight and upthrust, determining whether an object sinks or floats.

How do you calculate the resultant up thrust force acting on an object submerged in a fluid?

What happens to an object when the weight is greater than the up thrust?

In what scenario does an object float in a fluid?
