1. The electric field of 2.5 x 107 V/m can give 1 eV energy to condition electron, then in a copper block what will be the mean free path of electron?

The force on electron in eE. As the electron moves through distance d , the work done on it is eEd. This is equal to energy transferred to electron. ∴ eEd = 1 eV ∴ d = 4 x 10-7m.
