question 14

Multiple Choice

A container has a vertical tube, whose inner radius is 20.00 mm, connected to it at its side, as shown in the figure. An unknown liquid reaches level A in the container and level B in the tube-level A being 5.0 cm higher than level B. The liquid supports a 20-cm high column of oil, between levels B and C, whose density is $900 \mathrm {~kg} / \mathrm { m } ^ { 3 }$ The density of the unknown liquid is closest to

• A)3600 kg/ \(m ^ { 3 }\)
• B)3900 kg/ \(m ^ { 3 }\)
• C)2800 kg/ \(m ^ { 3 }\)
• D)3100 kg/ \(m ^ { 3 }\)
