If the work done in stretching a wire by 1 mm is 2 J, the work necessary for stretching another wire of the same material but with double radius of cross-section and half the length by 1 mm is
A U-shaped wire is dipped in a soap solution and removed. The thin soap film formed between the wire and light slider supports a weight of \( 1.5 \times 10^{-2} \, \text{N} \). The length of the slider is 30 cm. What is the surface tension of the film?
The Young's modulus of brass and steel are $10 \times 10^{10} \, \text{Nm}^{-2}$ and $20 \times 10^{10} \, \text{Nm}^{-2}$, respectively. A brass wire and steel wire of the same length are extended by 1 mm under the same force. If the radii of the brass and steel wires are $R_B$ and $R_S$ respectively, then
