A thin liquid film formed between a `U-`shaped wire and a light slider supports a weight of `1.5 xx 10^(-2)N`(see figure). The length of the slider is `30 cm` and its weight negligible. The surfaces tension of the liquid film is :

A thin liquid film formed between a U-shaped wire and a light slider supports a weight of 1.5xx10^-2N (see figure). The length of the slider is 30cm and its weight negligible. The surface tension of the liquid film is

A thin film of liquid is formed in a rectangular frame of wire and a light slider supports a weight of (2.5 * 10^-2)N .The length of slider is 20cm and its weight negligible. The surface tension is liquid is

A U-shaped wire is dipped in a soap solution, and removed. A thin soap film formed between the wire and a light slider supports a weight of 1.5xx10^(-2)N (which includes the small weigh of the slider). The length of the slider is 30cm. What is the surface tension of the film?

The surface tension of a thin liquid film formed between a U shaped wire and a light slider of length 30 cm supporing a weight of 1.5xx10^(-2)N is

A wire is bent in the form of a U -shape and a slider of negligible mass is connecting the two vertical sides of the U-shape. This arrangement is dipped in a soap solution and lifted a thin soap film is formed in t he frame it supports a wegith of 2.0xx10^(-2) if the length of the slider is 40 cm whta is the surface tension of the film?

A thin soap film is formed on a U shaped wire loop having a slider (of negliglibe mass) of length 10 cm. it is found that the film can support a weight of 0.012 N, before it breaks. What is the surface tension of the film ?

A thin wire ring of 3 cm radius float on the surface of liquid. The pull required to raise the ring before the film breaks is 30.14xx10^(3)N more than its weight. The surface tension of the liquid (in Nm^(-1)) is

The surface energy of liquid film on a ring of area 0.15 m^(2) is (surface tension of liquid 5Nm^(-1) )
