Question

What is the upward force exerted by fluids when any object, such as a boat, is placed in it?

Answer 1

bouyant force

Objects such as ships may float in a fluid like water because of buoyant force. This is an upward force that a fluid exerts on any object that is placed in it. Archimedes discovered that the buoyant force acting on an object equals the weight of the fluid displaced by the object. This is known as Archimedes law  or Archimedes principle .
