When a body hanging form a spring balance is immersed in water it floats just below the surface of water and shows 100 g loss in its water ? (1) what is the weight of the body in water? (2) what is the weight of the body in air? (3) what is the upthrust on the body? (4) what is the volume of the body? Give reason for your answers. Give: acceleration due to gravity at the place is 10 m s -2, volume of 1 g of water = 1 mL

  1. density of water = 1 gram/cm^3

    1. weight in water is 0

    2.volume = 100 cm^3 because it displaced 100 grams of water
    Therefore if neutrally buoyant it weights 100 grams in air.

    3. Buoyant force = 100 grams . That was given.

    4. volume = 100 cm^2 as we said
