Paragraph: A container contains three liquid as shown in the figure. The specific gravity of liquid I and liquid II are 0.8 and 1.2 respectively. The is small hole having area 10⁻⁶ ~m ^2 at point P as shown in the figure. Initially hole is closed. The cross-sectional area of container is 50 ~cm ^2 . Assume all liquids are ideal and neglect any type of friction between liquid and container. Read the passage carefully
