Water is filled up to a height h in a beaker of radius R as shown in the figure. The density of water is r, the surface tension of water is T and the atmospheric pressure is P0. Consider a vertical section ABCD of the water column through a diameter of the beaker. The force on water on one side of this section by water on the other side of this section has magnitude
- |2P0Rh + pR2rgh – 2RT|
- |2P0Rh + Rrgh2 – 2RT|
- |P0pR2 + Rrgh2 – 2RT|
- |P0pR2 + Rrgh2 + 2RT|.
Answer
(B) |2 P 0 Rh + R r gh 2 – 2 RT |
