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