A film of soap solution is formed between two straight parallel wires of length \(10 \mathrm{~cm}\) each separated by \(0.5 \mathrm{~cm}\). If their separation is increased by \(1 \mathrm{~mm}\) while still maintaining their parallelism. How much work will have to be done?
(surface tension of solution \(=65 \times 10^{-2} \mathrm{~N} / \mathrm{m}\) )
