A wire of length 'l' meters, made of a material or specific gravity 8 is floating horizontally on the surface of water. If it is not wet by water, the maximum diameter of the wire (in millimeters) up to which it can continue to float is (surface tension of water is T = 70 xx 10^(-3) Nm^(-1) )

A straight piece of wire 5 cm long is placed horizontally on the surface of water and gently pulled up. It is found that a force of 7 xx 10^(-3) N in addition to weight of wire is required for that purpose. The surface tension of water is

A dry clean needle of diameter 'd' and density p when carefully placed on the surface of water remains floating. If T is the surface tension of water, then maximum value for the diameter 'd' of the needle for enabling it to float will be
