1. Consider a cylindrical wire that has conduction electron density 6.0 x 1028 and radius 0.5 mm. An electric field with strength m- 7.5 x 10-4 creates a current of 4.8 x 10" electrons per second. a) What is the average drift speed for an electron? (include units) b) What is the average time in between electron collisions? fs (express your answer in femtoseconds)
