Q:

Two identical solid pieces, one of gold and other of silver, when immersed completely in water exhibit equal weights. When weighed in air (given that density of gold is greater than that of silver)

A) the gold piece will weigh more B) the silver piece will weighmore
C) both silver and gold pieces weigh equal D) weighing will depend on their masses
 
Answer & Explanation Answer: B) the silver piece will weighmore

Explanation:

As it is said that density of gold is greater than that of density of silver, so silver occupies a greater volume than gold. So it has more upthrust from the water, although they both show the same weight under water, there is more silver present. Hence silver piece will weigh more.
