Therefore, weight = 3.5 kgf
Volume of displaced water = 1000 cm3
(i) Volume of body = volume of the water displaced = 1000 cm3
Hence, the volume of body = 1000 cm3
(ii) Upthrust on body = volume of the body × density of water × g
= 1000 × 0.001 × g = 1 kgf
(iii) The apparent weight of body in water = true weight – upthrust
= 3.5 – 1
= 2.5 kgf
