Question

How is it decided that in object left in liquid will get sink in the liquid, will float on the surface, or will float inside the liquid?
1. The object floats if the buoyant force is larger than its weight.
2. The object sinks if the buoyant force is smaller than its weight.
3. The object floats inside the liquid if the buoyant force is equal to its weight.
Which forces are unbalanced in the above cases ?

Answer 1

When the buoyant force applied on an object is less than the weight of the object, the object sinks.
But when da buoyant force is greater than the weight of da object it float upward the layer of water

Answer 2

Hello dear,

● Answer -
Whether the object will float or sink or float inside the liquid is determined by balance between buoyant force & gravitational force (weight).
1) When buoyant force > gravitational force, the object will float on liquid.
2) When buoyant force < gravitational force, the object will sink in liquid.
3) When buoyant force = gravitational force, the object will float inside liquid.

The forces that maybe unbalanced are gravitational force (acting downwards) & buoyant force (acting upwards).

Hope this helps you. Thanks for asking..
