question 63

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) \(3600 \mathrm {~kg} / \mathrm { m } ^ { 3 }\)
• B) \(3900 \mathrm {~kg} / \mathrm { m } ^ { 3 }\)
• C) \(3100 \mathrm {~kg} / \mathrm { m } ^ { 3 }\)
• D) \(3300 \mathrm {~kg} / \mathrm { m } ^ { 3 }\)
