An unknown object is suspended from a thin string and fully submerged in a container of water. Water surrounds the entire object as it hangs from the string, and the object is not touching the bottom of the water filled container. The object remains at rest at all times. The density of water is 1000 kg/m3. a) Draw a FBD using the unknown object as your system. Be sure to label the forces. b) The unknown object has an unknown mass M. The tension in the string is measured to be (3/5)M g. Calculate the density of the unknown object.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

Question

An unknown object is suspended from a thin string and fully submerged in a container of water. Water surrounds the
entire object as it hangs from the string, and the object is not touching the bottom of the water filled container. The
object remains at rest at all times. The density of water is 1000 kg/m3. a) Draw a FBD using the unknown object as your
system. Be sure to label the forces. b) The unknown object has an unknown mass M. The tension in the string is
measured to be (3/5)M g. Calculate the density of the unknown object.
