What is net force on a cork floating on water?

When the cork is floating, its weight is balanced by the upthrust. Therefore, net force on the cork is zero.

What forces are acting on an object floating in water?

Two forces act on an object when it enters water: a downward force called gravity and an upward force called buoyancy.

What is the force for floating?

An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.

Why does a cork float?

Wood, cork, and ice float in water because they are less dense than water. It floats because it weighs less than amount of water it would have to push out of the glass if it sank. Wood, cork, and ice are all less dense than water, and they float; rocks are more dense, so they sink.

What is the magnitude and direction of the net force acting on a stone?

The net force acting on the stone is because of acceleration due to gravity and it always acts vertically downward. The magnitude of this force is 1 N. It is given that the train is accelerating at the rate of 1 m/s2. This force is acting in the horizontal direction.

How do we float in water?

As long as the water your body displaces weighs more than you do, you float. This is, in short Archimedes’ Law. A human submerged in water weighs less (and is less ‘dense’) than the water itself, because the lungs are full of air like a balloon, and like a balloon, the air in lungs lifts you to the surface naturally.

Why do things float on water?

Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. When an object floats, it pushes water out of the way ( displacement ).

Does cork float in water?

Solution: A piece of cork floats on water because the density of cork is less than the density of water whereas an iron nail sinks in the water because the density of iron nail is more than the density of water.

What is the magnitude and direction of the net force acting on a cork of mass 10 gram floating on water?

As the cork is floating on water, it’s weight is being balanced by the upthrust which is equal to the weight of the water displaced. Hence, net force acting on the cork is zero.

What is the magnitude of the net force acting?

The magnitude of the net force acting on an object is equal to the mass of the object multiplied by the acceleration of the object as shown in the formula below.
