What is the drift velcity of electrons in silver wire of length 1 m having cross-sectional area `3.14xx10^(-6)m^(2)` and carrying a current of 10 A . Given atomic mass of silver =108, density of silver `=10.5xx10^(3) kg m^(-3)`, charge on electron `=1.6xx10^(-19) C` and Avogadro's number `=6.023xx10^(26)` per kt-atom.

Answer

`3.999xx10^(-4) ms^(-1)`
