Buoyant Force
A Buoyant Force on any object is force acting in upward direction which is immersed in a liquid .The force is produced by the pressure applied on the body sinks or floated in a liquid.
A body to float or sink in a liquid due to the presence of buoyant force.
An object floats under positive buoyant force
The force created by the pressure exerted by the bottom of the liquid under pressure produces force is more than the surfacial force
An object sinks under negative buoyant force
The bottom of the liquid under pressure produces force is less then the force produced by the top of the liquid.
An object sinks nor float under neutral buoyant force,if force produced is equal to gravitational force.
