A stone of mass 1.3 kg is being rotated ...

A stone of mass 1.3 kg is being rotated in a horizontal plane as a conical pendulum with the help of a 140 cm long aluminium wire of cross - sectional area `1mm^(2)`. The wire makes an angle `theta=75^(@)` with the vertical. What is the increment in the length (in mm) of the wire? `["Young's modulus of aluminium " Y_(Al)=7xx10^(10)"N m"^(-2), sin 75^(@)~~0.97, cos 75^(@)~~0.26, g=10ms^(-2)]`
