solution.On it a thread is placed in the form of a loop. The film is pierced inside the loop and the thread becomes a circular loop of radius R. If the surface tension of the loop be T, then what will be the tension in the thread. a)π(r^2)/ T b)π(R^2) T c)2 R T d)RT My answer is d) RT but I don`t have an answer key and the solutions I`ve seen are contradicting {doubt between (c) or (d)}. I just want to verify my answer
