Question

a cube of copper and a spherical ball of iron having same volume were immersed in salty water. Find the realtion between buyonat force acting on both objects with reason. explain ot properly.

Answer 1

The buoyant force will be the same as
B=V(i)×rho(w)×g
Where V(i) is the volume of the object
rho(w) is the density of water(salty)
And g is acceleration due to gravity
It is given the volume is same
Therefore the buoyant force is same
It does not depend on the nature of material
Due to the different shapes the force may act differently
