Q4 · Physics
A U tube with both ends open to the atmosphere, is partially filled with water. Oil, which is immiscible with water, is poured into one side until it stands at a distance of 10 mm above the water level on the other side. Meanwhile the water rises by 65 mm from its original level (see diagram). The density of the oil is :
The figure, described in words
U-tube open to atmosphere (Pa) at both ends: oil column in left arm, its top 10 mm above final water level in right arm; water rose 65 mm above initial level, and the oil-water interface is 65 mm below initial level.
