Give Reasons for the following:Will the magnitude of up thrust change

1.	Give Reasons for the following:Will the magnitude of up thrust change when more and more volume of a rigidbody is immersed in water? When does this up thrust become minimum?
Answer» The up thrust is equal to the weight of water displaced when the object is immersed in it. More the volume of submerged part of rigid body, more is the water displaced and thus more is the up thrust. When the density of body is equal to the density of the water, the up thrust is minimum because the object just floats.

Answer»

The up thrust is equal to the weight of water displaced when the object is
immersed in it. More the volume of submerged part of rigid body, more is the water
displaced and thus more is the up thrust.

When the density of body is equal to the density of the water, the up thrust is minimum
because the object just floats.
