Shape of surface
Consider a large container filled with water. Let the surface tension of water be \(T\). Find the equation of the surface of the water.
- The slope of the surface at every point is small so that the assumption \(\theta=\sin\theta=\tan\theta\) can be made.
- The difference in pressure just above and just below the surface is same everywhere and is \(P\).
- The lowest point on the surface is the origin
