A loop of \( 6.28 \mathrm{~cm} \) long thread is put gently on a soap film in a wire loop. The film is pricked with a needle inside the soap film enclosed by the thread. If the surface tension of soap solution is \( 0.030 \mathrm{~N} / \mathrm{m} \), then the tension in the thread ishttps://bit.ly/YTAI_PWAP https://www.pw.live
