361250 The excess pressure inside a soap bubble is thrice the excess pressure inside a second soap bubble. The ratio between the volume of the first and the second bubble is

361251 A bowl whose bottom has round holes of diameter \(1\,mm\) is filled with water. Assuming that surface tension acts only at holes, find the maximum height up to which water can be filled in the vessel without leakage. (Given, surface tension of water \({=75 \times 10^{-3} {Nm}^{-1}, g=10 {~ms}^{-2}}\) and density of water \({=1 {~g} / {cm}^{3}}\).

361252 Assertion :
Water drops take spherical shape when falling freely.
Reason :
Water has minimum surface tension among all liquids.

361253 In air, a charged soap bubble of radius ' \(R\) ' breaks into 27 small soap bubbles of equal radius ' \(r\) '. Then the ratio of mechanical force acting per unit area of big soap bubble to that of a small soap bubble is
