The area of cross section of the rope used to lift a load by a crane is $\displaystyle 2.5 \times 10^{-4} \mathrm{~m}^2$. The maximum lifting capacity of the crane is $\displaystyle 10$ metric tons. To increase the lifting capacity of the crane to $\displaystyle 25$ metric tons, the required area of cross section of the rope should be : (take $\displaystyle g=10 \mathrm{~ms}^{-2}$ )
