Water is flowing through a horizontal pipe in a streamline flow. At the narrowest part of the pipe

Work done to get ' $n$ ' spherical drops of equal size from a single spherical drop of water, is proportional to

A light metal disc of radius ' $r$ ' floats on water surface and bends the surface downwards along the perimeter making an angle ' $\theta$ ' with the vertical edge of the disc. If the weight of water displaced by the disc is ' W ', the weight of the metal disc is [ $\mathrm{T}=$ surface tension of water]
