Question

will the weight of an object completely submerged in water remain same throughout the liquid withvarying depths?

Answer 1

Yes. When an object is immersed fully in water the buoyant force on the object is equal to the weight of the volume of water displaced by the object. So, whatever be the position of the object inside the liquid the water displaced remains same. Hence, the upward thrust or buoyant force remains same everywhere inside the water. Now, apparent weight of the object is equal to actual weight minus the upthrust. Since, actual weight is constant and in this case the upthrust is also constant, so, the weight of the object will remain same throughout the liquid with varying depths.
