Question

Suppose you are finding the weight of a beaker of water, and you have it on the balance and are ready to record the weight. Your partner dips the tip of his or her pen in the water, but does not touch the beaker or the balance. Does the presence of the pen affect the reading on the balance? If so, how? If not, why not?

Answer 1

Answer:

Yes it would

Explanation:

The submerged portion of the pen would be affected by water buoyancy force which equals to the water weight that it displaces. By Newton's 3rd law, the pen would then make a reaction force on the water itself, which in turn affect the whole reading on the balance.

Answer 2

Yes, it would: The submerged part of the pen would be influenced by water buoyancy force which equals the water weight that it replaces.

What is Newton's Third Law?

The submerged part of the pen would be influenced by water buoyancy force which equals the water weight that it replaces. According to Newton's 3rd law, the pen would then make a reaction force on the water itself, which in turn impacts the whole reading on the balance.

Newton's Third Law refers to There are two forces resulting from this interaction. A force on the chair and also a force on your body. These two forces are called action and reaction forces and also are the subject of Newton's third law of motion.
