Question

Consider a beaker filled partially with water sitting on a scale. The scale reads wb, the total weight of the beaker and its water in air  An object of mass m and volume V attached to a massless string is then lowered into the water until it is fully submerged  The scale now reads wb* > wb.           
        
1. Show that the buoyant force B acting on the object is given by B = wb* ? wb.

      
2. Show that the volume V of the object is given by  

V = wb *?wb / g ? water

where ? water is the density of the water and g the acceleration of gravity.

      
3. Show that the density ? of the object is given by   
? =  mg ? water  /   wb *?wb
