361136 A glass capillary tube is of the shape of truncated cone with an apex angle \(\alpha\) so that its two ends have cross-sections of different radii. When dipped in water vertically, water rises in it to a height \(h\), where the radius of its cross-section is \(b\). If the surface tension of water is \(S\), its density is \(\rho\), and its contact angle with glass is \(\theta\), the value of \(h\) will be ( \(g\) is the acceleration due to gravity)
