369853 The following four wires of length \(L\) and radius \(r\) are made of the same material. Which of these will have the largest extension, when the same tension is applied?

369854 A wire elongates by \(l\;mm\) when a load \(W\) is hanged from it. If the wire goes over a pulley and two weights \(W\) each are hung at the two ends, the elongation of the wire will be (in \(mm\))

369855 The Young's modulus of a steel wire of length \(6\;m\) and cross-sectional area \(3\;m{m^2}\), is \(2 \times {10^{11}}\;N/{m^2}\). The wire is suspended from its support on a given planet. A block of mass \(4\;kg\) is attached to the free end of the wire. The acceleration due to gravity on the planet is \(\dfrac{1}{4}\) of its value on the earth. The elongation of wire is (Take \(g\) on the earth \( = 10\;m{s^{ - 2}}\))
