One end of a wire 2m long and 0.2 cm^2 in cross section is fixed in a ceiling and a load of 4.8 kg is attached to the free end. Find the extension of the wire. Young modulus of steel `=2.0xx10^11Nm^-2`. Take `g=10ms^-2`.

Explanation

To find the extension of the wire when a load is applied, we can use the formula derived from Young's modulus:

\[ \Delta L = \frac{T \cdot L}{A \cdot Y} \]

Where:
- \(\Delta L\) = extension of the wire
