26.

The mean free path of conduction electrons in copper is about 4 x 10^-8 m. For a copper block, find the electric field which can give, on an average, 1 eV energy to a conduction electron

2.62 x 10⁷ V/m

2.64 x 10⁷ V/m

2.5 x 10⁷ V/m

2.58 x 10⁷ V/m

Answer: Option

Explanation:

Work (Energy) = F x d

1 eV = e.E x d

2.5 x 10⁷ V/m.
