Statement-1: Leaves and small insects float on the surface of water buoyed up by archimede's principle
Statement-2: They are not partially submerged. The object are kept afloat by surface tension.

A small piece of wire of length 4 cm is floating on the surface of water. If a force of 560 dynes in excess of itss apparent weight is requried to pull it up from the surface find the surface tension of water.

Statement I: A needle placed carefully on the surface of water may float, whereas the ball of the same material will always sink. Statement II: The buoyancy of an object depends both on the material and shape of the object.

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) )

Statement-1:Alkanes float on the surface of water Statement-2: Density of alkanes is in the range of 0.6-0.9 g/ml , which is lower than water.
