A block weight is `15` Newton in air. It weight `12` Newton when immersed in water. When immersed in another liquid, it weight is `13` Newton. Then find the ratio of density of block an the other liquid. `(rho "block"//rho "liquid")`

Text Solution

Verified by Experts

(i) Relative density of body `=(W_("air"))/(W_("air")-W_("water"))`
where `W_("air")=15N` (weight of the body in air)
and `W_("water")=12N` (weight of the body in water)
`:.R.D_(B)=(15N)/(15 N-12N)=5`
(i) `R.D_(L)=("loss in weight in liquid")/("loss in weight in water")=(15-13)/(15-12)=2/3`
