A wire of length `L` metres, made of a material of 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 mm) upto which it can continue to float is (surface tension of water is `T=70xx10^(-3)Nm^(-1)`)

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) )

The material of wire has specific gravity 8. It is not wetted by water, what is the maximum diameter of the wire that will float on the surfacve of water?

A wire 10 cm long is placed horizontally on the surface of water. It is gently pulled up with a force of 1.4 xx10^(-2) N to keep It in equilibrium . The surface tension of water is
