To find the surface tension of the soap film formed in the U-shaped slider, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Given Values**: - Weight (W) supported by the soap film: \( W = 2.0 \times 10^{-2} \, \text{N} \) - Length of the slider (L): \( L = 40 \, \text{cm} = 0.4 \, \text{m} \) ...
