When a bar of length '$$l$$' and diameter 'd' is rigidly fixed at the upper end and hanging freely, then the total elongation produced in the bar due to its own weight is (where w = Weight per unit volume of the bar)?

$$\frac{{{\text{w}}l}}{{2{\text{E}}}}$$
$$\frac{{{\text{w}}{l^2}}}{{2{\text{E}}}}$$
$$\frac{{{\text{w}}{l^3}}}{{2{\text{E}}}}$$
$$\frac{{{\text{w}}{l^4}}}{{2{\text{E}}}}$$
