Question

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.

Options

A) 1.6cm

B) 16.0cm

C) 20.0cm

D) 25.0cm

The correct answer is D.

Explanation:

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

h=20
0.8
=25cm
