Length of copper wire, l = 785 meters
Explanation:
Given that,
Resistance of the copper wire, R = 0.172 ohms
Area of cross section,![A=7.85\times 10^{-5}\ m^2](/tpl/images/0043/9563/3d3af.png)
Resistivity of copper,![\rho=1.72\times 10^{-8}\ \Omega-m](/tpl/images/0043/9563/9f637.png)
The resistance of a wire is given by :
l = 785 meters
So, the length of the copper wire is 785 meters. Hence, this is the required solution.
