Figure shows the container of radius `R` filled with water. Consider an imaginary diametric line drividing the surface in two parts: Left half and right half. Find surface tansion force between the left half surface and the right half surface.

Text Solution

Verified by Experts

Both left half and right surface will pull each other with a force
`F = (T)(l)`
where `l` is the length of boundary lines between the two surfaces which is equal to `2R`
So `F = (T)(2R)`
