1. Answer:

   Given:

   Volume of the body =100 cm

   3

   Weight of the body in air, W

   1

   =1 kgf or 1000 gf

   Let weight of the body in water be W

   2

   We know that R.D. of water is 1 and that of a solid is 10

   To find the weight of the body in water

   Relative density of the body =

   W

   1

   −W

   2

   W

   1

   × relative density of water

   10=

   1000−W

   2

   1000

   ×1

   10(1000−W

   2

   )=1000

   W

   2

   =1000−100=900 gf
