	A spherical drop of water has radius 1 mm If surface tension of water is $70\times {{10}^{-3}}$N/m difference of pressures between inside and out side of the spherical drop is
	The pressure at the bottom of a tank containing a liquid does not depend on
	In capillary pressure below the curved surface of water will be
	Two soap bubbles of radii ${{r}_{1}}$ and ${{r}_{2}}$ equal to 4 cm and 5 cm are touching each other over a common surface ${{S}_{1}}{{S}_{2}}$ (shown in figure). Its radius will be
	The pressure inside a small air bubble of radius 0.1 mm situated just below the surface of water will be equal to [Take surface tension of water $70\times {{10}^{-3}}N{{m}^{-1}}$ and atmospheric pressure = $1.013\times {{10}^{5}}N{{m}^{-2}}$]
	Two bubbles A and B are joined through a narrow tube. Then
	Two soap bubbles have different radii but their surface tension is the same. Mark the correct statement
	If the excess pressure inside a soap bubble is balanced by oil column of height 2 mm, then the surface tension of soap solution will be (r = 1 cm and density d = 0.8 gm/cc)
