How. many types of bouyancys are there

There are three types of buoyancy which are positive, negative and neutral.

Positive buoyancy occurs when an object is lighter than the fluid it displaces. The object will float because the buoyant force is greater than the object's weight.

Negative buoyancy occurs when an object is denser than the fluid it displaces. The object will sink because its weight is greater than the buoyant force.

Neutral buoyancy occurs when an object's weight is equal to the fluid it displaces ...
