Two pieces of equal masses of lead and copper are immersed in liquid. Which will weigh more?

Solution

Density of copper is less than that of lead so, for the same mass copper occupies more volume than lead and hence, copper will experience more buoyant force than lead. Thus, copper will weigh less in liquid than lead.
