In a metal, the charge carrier density is 9.1×1028m−3 and its electrical conductivity is 6.4×107Sm−1. When an electric field of 10NC−1 is applied to the metal, then the average time between two successive collisions of electrons in the metal is (. Mass of electron =9.1×10−31‌kg; charge of electron =1.6×10−19C)
