A metallic block weighs `15 N` in air. It weights `12 N` when immersed in water and `13 N` when immersed in another liquid. What is the specific gravity of the liquid?

A

`5,(2)/(3)`

B

`(2)/(3),5`

C

`(4)/(5),5`

D

`5,(4)/(5)`

Text Solution

Verified by Experts

The correct Answer is:
A
`"RD of body = R.D."=(W_("air"))/(W_("air")-W_("water"))`
`"RD of liquid"=(W_("air")-W_("liquid"))/(W_("air")-W_("water"))`
