Water And Kerosine Are Drawn Respectively Into The Two Limbs Of A Hare's Apparatus. The Destiny Of Water Is 1.0gcm−3 And The Density Of Kerosine Is If The Height Of The Water Column Is 20.0cm, Calculate The Height Of The Kerosine Column.

A. 1.6cm
B. 16.0cm
C. 20.0cm
D. 25.0cm

Correct Answer: Option D

Explanation

Devices with different liquids

d1h1 = d2h2
1 × 20 = 0.8 × h

h = 20/0.8
= 25cm

Water and Kerosine are drawn respectively into the two limbs of a Hare’s apparatus. The destiny of water is 1.0gcm−3 and the density of kerosine is 0.80gcm−3. If the height of the water column is 20.0cm, calculate the height of the kerosine column.
