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.

A.

1.6cm

B.

16.0cm

C.

20.0cm

D.

25.0cm

Correct answer is D

Devices with different liquids
d\(_1\)h\(_1\) = d\(_2\)h\(_2\)
1 × 20 = 0.8 × h

h = 20
0.8
= 25cm
