Question

Two solid pieces, one of gold and the other of silver when immersed completely in water have equal weights. When weighted in air:

  1. the gold piece open parentheses rho subscript text gold  end text end subscript less than rho subscript text silver  end text end subscript close parentheses will weigh more than silver
  2. the silver piece will weigh more than gold
  3. they will have the same weight
  4. both of them weigh less than they weighed in water

The correct answer is: the silver piece will weigh more than gold


    Suppose, weight of gold in air =x g.
    Weight of silver in air = yg
    Density of gold = d1
    Density of silver = d2 (where d subscript 1 greater than d subscript 2)
    Volume of gold equals x over d subscript 1, volume of silver equals x over d subscript 2
