A body weighs `500` gf in air and `300` g f when completely immersed in water. Find
(a) the apparent loss in the weight of the body,
(b) the upthrust on the body (c ) the volume of the body.

Explanation

Weight of the body in air `W_(1)=500` g f
Weight of the body in water `W_(2)=300` g f
(a) Loss in weight of the body `=W_(1)-W_(2)`
`=500g f -300 g f =200 g f`
(b) Upthurst on the body `=` Loss in weight of the body `=200` gf
(c ) Volume of the body `=` Volume of the liquid displaced `=200cm^(3)`
( `:.` density of water `=1 gm//"cc"^(3)`)
