A wire of mass `1g` is kept horizontally on the surface of water. The length of the wire that does not break the surface film is (surface tension of water is `70dynecm^-1`)

A wire of mass 1g is kept horizontally on the surface of water. The length of the wire that does not break the surface film is (surface tension of water is 70dyne cm^-1 )

A wire of mass 5 gm is kept horizontally on the surface of water. What ist he minimum length of the wire so that it does not break the surface film.Surface tension = 72 xx 10^(-3)N//m

The surface tension of pure water is

A metalic wire of diameter d is lying horizontally o the surface of water. The maximum length of wire so that is may not sink will be

A metallic wire of diameter d is lying horizontally on the surface of water. The maximum length of wire so that it may not sink will be

Detergents ………… the surface tension of water.

A metallic wire of diameter “d” is lying horizontally on the surface of water. The maximum length of wire so that is may not sink will be

A needle of 12 cm length is on the surface of water. The extra force required, over its weight, to take it out form the surface of water is (surface tension = 72 dyne cm^(-1) )

A wire of mass 0.3 gm is lying horizontal on the surface of water. The maximum length of wire so that it may not sink, will be (T=70xx10^(-3)N//m)

A platinum wire ring of radius 2.5 cm floats horizontally on the surface of water. A vertical force of 0.022 N is required to detach the ring from the surface of water. Then surface tension of water is.
