In the hare's apparatus, water rises to a height of 26.5 cm in one limb. if a liquid rises to a height of 20.4 cm in the other limb, what is the relative density of the liquid?
0.8
1.1
1.2
1.3
Explication
hlpl = hwpw
where, L =liquid and W = water
(pl)/pw = (hw)/hl = (26.5)/20.4
= 1.299

(pl)/pw = (hw)/hl = (26.5)/20.4
= 1.299
