A capillary tube of radius `'r'` and height `h_(1)` is connected to a broad tube as shown in fig. The broad tube is gradually filled with drops water falling at equal intervals. Plot the changes in the levels of the water in both tubes with time and changes in the difference between these levels. Calculate the maximum water level in the broad-tube and maximum difference in levels. The surface tension of water is `alpha`.

Answer

`(##RES_WFPM_PHY_XI_C02_E01_087_A01##)`
Maximum height `= h_(1) + h_(0)`
Maximum difference in level `= h_(0)` where `h_(0) = (2alpha)/(dgr)`.
