1.	Water rises up to a height h in a certain capillary tube of a particular diameter. Another capillary tube is taken whose diameter is half that of the previous tube. The height up to which water will rise in the second tube is
Answer» `3h` `2H` `4h` `h` SOLUTION :As `h prop 1/R, so (h)/(h.)=(r.)/(r)` Here, `r.=(r)/(2) or, r=2r.` `THEREFORE (h)/(h.)=(r.)/(2r.) or, h.=2h`
