A body weighs 500 gf in air and 350 gf when
completely immersed in water. Find the
(a) volume of the body,
(b) loss in weight of the body,and
(c) upthrust on the body

​

Answer 1

(b) Loss in weight of the body.

Answer 2

Explanation:

Weight of body in air = 450 gf

Weight of body in water = 310 gf

(i) Volume of the body Loss in weight x

density of water

= (450 - 310) x 1 [Assumption : density of

=

water = 1 "g cm"A-3']

= 140 "cm"^3

(ii) Loss in weight Weight of body in air - = Weight of body water

= (450 - 310) gf =

= 140 gf

(iii) Upthrust on body = loss in weight = 140
