361216 On heating water, bubbles beings formed at the bottom of the vessel detach and rise. Take the bubbles to be spheres of radius \(R\) and making a circular contact of radius \(r\) with the bottom of vessel. If \(r < < R\) and the surface tension of water is \(T\), value of \(r\) just before bubbles detach is (density of water is \(\rho\) )

361217 There is a small hole in a hollow sphere. When it is taken to a depth of \(20\;cm\) under water, water enters in it. If the surface tension of water is \(0.07\;N{\rm{/}}m,\) the radius of the hole in \(\mu m\) is
(Take \(g = 10\;m{\rm{/}}{s^2}\))

361218 A soap bubble with a radius ' \(r\) ' is placed on another bubble with a radius \(R\) (figure). Angles between the films at the points of contact will be
