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?

Explanation

To find the surface tension of the soap film formed between the U-shaped wire and the light slider, we can follow these steps:

### Step 1: Understand the Problem
We have a U-shaped wire dipped in a soap solution, and when removed, it forms a thin soap film. The film supports a weight of \(1.5 \times 10^{-2} \, \text{N}\). The length of the slider is given as \(30 \, \text{cm}\).

### Step 2: Convert Length to Meters
Since the standard unit of length in physics is meters, we need to convert the length of the slider from centimeters to meters:
