The depth of immersion of hydrometer in ...

The depth of immersion of hydrometer in water is 10 cm. What will be the depth of immersion in a liquid whose density is `2 g cm^(-3) `?

Text Solution

Verified by Experts

Relative density is equal in magnitude to the density of substance in c.g.s. system.
`therefore` R.D. of a given liquid =density of liquid in c.g.s. system.
R .D. =2
R.D =`(h_w)/(h_l)`
2=`(10cm)/(h_l)`
`therefore h_l=5 cm`
