A 1 m long copper wire carries a current of 1 A. If the cross section of the wire is 2.0 mm^2 and the resistivity of copper is 1.7 × 10^-8 Ω m, the…
A $\displaystyle 1$ m long copper wire carries a current of $\displaystyle 1$ A . If the cross section of the wire is $\displaystyle 2.0 \mathrm{~mm}^2$ and the resistivity of copper is $\displaystyle 1.7 \times 10^{-8} \Omega \mathrm{~m}$, the force experienced by moving electron in the wire is \_\_\_\_ $\displaystyle \times 10^{-23} \mathrm{~N}$.
(charge on electorn $\displaystyle =1.6 \times 10^{-19} \mathrm{C}$ )
