When an object floats the forces of weight and the force of upthrust are?

They must be equal. We know that, because if the vertical forces on the object
didn't add up to zero, then it would be accelerating vertically, either up or down.

What is cause of upthrust force?
It is when an object floats due to balanced force between upthrust of the fluid (pushing upwards) and weight of the object (pushing downwards).
Does upthrust reduces the weight of an object?
No, the weight and upthrust are two different forces acting on an object. If both weight and upthrust are acting on an object, the total resultant force is the two added together, but weight is solely a product of the mass (which remains unchanged, unless you take into account special relativity, but I'm guessing we're not in this instance) and acceleration acting on the given object, which remains the same.
What are the two forces that act on a stationary boat that is afloat?
The two forces that act are the weight of the boat (mass times gravity) and the upthrust of the water. If the boat is in equilibrium on the water (e.g. not sinking) then upthrust will equal weight
What is bouyancy force always equal to?
Buoyancy force or upthrust must be equal to the weight of the object for the object to stay afloat. If the weight is greater than the upthrust, the object would sink.
What happens if the buoyant force on an object is less than the weight of the object?
You go up. This is how a balloon works. As you go higher, the air gets thinner and the upthrust gets smaller. Eventually you don't go any higher.

What happens to the body when the upthrust is less than the weight of the object'?
An object that is COMPLETELY submerged in water has its Upthrust equal its weight, but it doesn't necessarily float, an object could be at the rock-bottom of the ocean, and it would still have its upthrust equal to its weight. This is because the upthrust is equal to the weight of the fluid displaced, and so while the objects volume remains constant, and assuming the density of the fluid it displaces is constant.. The upthrust remains constant, this is unless the object compresses and has its density altered.. I know I didn't directly answer your question, but I hope this helps.. Even if a little.

What are the reason why some things float in the water?
Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.

You go up. This is how a balloon works. As you go higher, the air gets thinner and the upthrust gets smaller. Eventually you don't go any higher.
The force is equal to the weight of the fluid displaced by an object?
Upthrust.
Why does an object seem lighter in water?
because of the upthrust in water it weighs less and floats. An object in water will recieve an upthrust equal to the weight of water it displaces . submarines when neutrally ballasted could hang by the periscope that is just under the water raise periscope sub sinks down as water covers periscope starts to rise again, Any floating object displaces its own weight of fluid.
The gravitational force exerted on an object?
Is called upthrust it represents you doing something and the weight of upthrust pulling you up
What is the effect of water on object submerged in water?
It is named as buoyant force which always acts in the upward direction ie opposite to the weight of the body. So actual weight appears to be reduced. Hence apparent weight loss
An object will float in water if it weighs?
a weight equal to the upthrust of the water
