The length of a wire is `l_1` , when tension is `T_(1)` and is `l_2` when tension is `T_2` The length of the wire without any tension is

`(l_2T_1-l_1T_2)/(T_1-T_2)`

`(l_1T_1-l_2T_2)/(T_1-T_2)`

`(l_1T_1)/(T_2-T_1)`

`(l_2T_2)/(T_1-T_2)`

The length of a metal wire is L_1 , when the tension is T_1 and l_2 when the tension is T_2 . The unstretched length of the wire is

The length of a metallic wire is l_1 metre when the tension is 4 N and l_2 metre when the tension is 6N respectively. Find the length when the tension is 9N and the actual length of the wire.

Let L be the length and d be the diameter of cross section of a wire. Wires of the same material with different L and d are subjected to the same tension along the length of the wire. In which of the following cases, the extension of wire will be the maximum? L= 200 cm, d=0.5 mm L= 300 cm, d=1.0 mm L= 50 cm, d= 0.05 mm L=100 cm, d=0.2 mm

A uniform wire has length l and area of cross section alpha and the density of its material is rho . If the wire is stretched with a tension T , what would be the velocity of a transverse wave travelling along it ?

A wire of length 25 cm and mass 2 . 5 g is stretched with a fixed tension. The length of a pipe closed at one end is 40 cm . During vibrations, the first overtone of the wire produces 8 beats per second with the fundamental emitted by the pipe . The number of beats reduces with the decrease in tension in the wire. If the velocity of sound in air is 320 m*s^(-1) , find the tension in the wire.
