Floating objects (weight that depresses the surface)


When an object is placed on a liquid, its weight depresses the surface, and is balanced by the surface tension forces on either side , which are each parallel to the water’s surface at the points where it contacts the object.The object’s surface must not be wettable for this to happen, as well as the weight should be lower than the surface tension can hold.
