A minute spherical air bubble is rising slowly through a column of mercury contained in a deep jar. If the radius of the bubble at a depth of is , calculate its depth where its radius is , given that the surface tension of mercury is . Assume that the atmospheric pressure is of mercury.
View answer and explanation
Correct option: A
Option A () is correct because it is calculated by applying Boyle's law and considering the pressure due to depth and surface tension.
