Question

on which factor the magnitude of the upward force acting on this object depends

Answer 1

Density of the liquid is a primary factor that determines the quantity of the upward force.

Due to high specific density, the amount of the liquid displaced by the object is far more than that of the substance with lower density.

It results in an increase in the upward thrust and keeps the body floating over the water.

Answer 2

1) Density of fluid

2)Weight of the object ( due to Archimedes Principle)
