A mild steel bar is in two parts having equal lengths. The area of cross section of Part-I is doubled that of Part-II. If the

bar carries an axial load $' p'$ , then the ratio of elongation in part-I to that in part-II will be

- 1
  
  $2$
- 2
  
  $4$
- 3
  
  $\frac{1}{2}$
- 4
  
  $\frac{1}{4}$
